Are more important...legs or arms in swimming?
When you get to a high level of ability you can tell the difference between the muscles used. I'll talk about arms here. What most people probably don't know is that your abdominal and lower back muscles (I don't know their names) are more powerful than the muscles in your upper shoulders and arms. What this means is, if you're swimming at a moderate pace, your arms will be doing the work (forget the legs for a second). But if you move your arms more quickly and take faster strokes (obviously to move faster) your abdominal and lower back muscles on your sides move you through the water and are better at doing so than your arms. Think of your arms as anchors that you must pass, like buoys in the water, not as pulling devices, because if you have the technique correct, your arms will simply be "anchoring" you ahead and your core muscles will power you through. It's a lot more labor intensive though (duh). I'm not as strong in my legs as in my arms but I can definitely tell the difference between "using" my arms and "using" my core muscles when I really put on the fire. For me, arms are more important.
What's more important, turning 18 or turning 21?
at the age of 18 you are considered to be a legal adult. You can go out on your own, you can get a job without a work permit, you can vote, you can join the military if you want. It is the beginning of adulthood. That's certainly much more important than turning 21. There is nothing big about being 21 except for the fact that it's the legal drinking age, that's nothing great or important
Is it more important to keep warm when SCUBA diving or free diving?
Yes it is more important. Why?While scuba diving your body accumulates inert gas. usually Nitrogen, and in some cases nitrogen and Helium if the diver is diving with trimix instead of air.While freediving, the amount of gas the body accumulates can be neglected. No decompression stops are needed.So a SCUBA diver will have a gas uptake in the blood and tissues. This gas comes from the lungs, goes to the blood, and out to the other tissues in the body while the diver is decending and being on the bottom. At the beginning of a scuba dive, the diver is warmer then at the end of the dive. That means that at the end of the dive, the body will have less circulation of blood near the skin. The body protects itself from the cold by shutting of circulation to fingers, feet etc. Now the problem is that at the beginning of the dive we had circulation in these extremities, so inert gas has been stored there.. transported there by the blood flow. At the end of the dive when we are transporting ourselves to a lesser depth, and the preassure decreases the tissues that have been loaded with inert gas, need to return these to the blood, so it can be ventilated out again through the lungs. But since the blood flow is less, its harder for these extremities to ventilate the stored inert gases.Cold water diving is therefore a bigger risk of getting the bends, or decompression sickness. From an ongas/offgas standpoint it would be much better if we somehow could start the dive being really cold, and then during the ascent get warmer.. But as others have pointed out, Diving should be enjoyable.
What does "no U-turn" mean? What is its importance?
A ‘’No U-Turn” sign is common in towns where there is two way traffic and the median isn’t wide enough for a vehicle to slow on the left lane (or their lane, in a two lane situation) and turn around into the opposite lane going back the way they came. Since they are (or may be) holding up traffic behind them, and may pull out into traffic going the opposite direction, some jurisdictions prohibit the action. The reason, simply put, for a no u-turn policy is to improve traffic flow and make driving safer for everyone.If you need to reverse direction, you should be able to take a side street, circle the block, and turn the direction you need to go when you intersect the highway you were traveling on again.There are a number of ways the action of making a u-turn can be dangerous. When executing a u-turn at a traffic light, for example, you may confuse a vehicle making a right turn onto the street you are returning onto when they have a right turn right-of-way either at a stop sign or signal light.The statements of right or left lane, and right turn, apply to locations where traffic travels on the right lane, the reverse would be true for locations where people drive in the left lane, such as in Britain.
Is 'Hiring" the most important thing that managers should do as recommended in the book "How Google Works"?
I would say not, myself coming with past experience as a manager, a company director and a business owner/operator. Hiring might be the most important thing that managers at Google should do. In most companies I've come across and in my previous companies, it usually turns out giving direction and development to their work and employees is more important over the long term.Having said that, hiring is one of the more important aspects of a manager's responsibility, since the employee is the actual person 'on the ground' who has to get the work done. If that employee isn't the right one for that, then the manager is failing in part of his mission as a manager.
Why is diving fun?
For me, diving is fun because:It feels like I can fly! When your buoyancy is perfect, you can tumble and soar through the water in a way that (I imagine) simulates moving in zero gravity. I'm never going to make it into space, so this is as close as I can get;Coral reels are breathtakingly beautiful. I am interested in biodiversity, and you can only a sample a portion of our planet's riches above the surface. Diving in Raja Ampat in Indonesia allowed me to see the second-most biodiverse spot on the plant in all it's glory;There's more of the planet under the water than on top of it. Why miss out?;Fish aren't scared of us. Seriously, it's a bit humbling to go under the water only to find out that nothing down there is the least bit impressed by us. They just keep going about their business and only move far enough out of the way to not run into us. Land animals do not react like this. Fish and invertebrates under water remind us that we aren't really that important; andThe diving community unites the world. Even without a language in common, when you dive with others, you share responsibility for each other's safety. We check each other's gear, watch over each other, and help each other no matter WHAT. This instant connection has allowed me to interact with people around the globe in a way that never fails to touch me.
Which is more important, family or career?
Extremely few people ever want to live unmarried. Most people get married/ want to get married in order to have a loving relationship with the spouse, have a nice family, rear children, have basic comforts in life, enjoy some luxuries, have a peaceful retired life and have your life and comforts taken care of by children at old age.Yes; there are hiccups that happen in married life; husband-wife relationship gets strained; lots of fights happen; Children become disobedient; children go astray; loans eat up your life; children leave abroad to chart their own life and discard parents at old age. But, people still really want to cling to family life and derive some joy out of it. They get divorced because the relationship between the spouses get beyond repair; they want to get remarried because they want the love and intimacy with the spouse as a basic need in a family set up. The children are to be taken care of, either born at previous wedlock or at new wedlock.Thus everything revolves around family. The very purpose of working and earning money is predominantly to run the family. When the family life is smooth and cordial, when there is love and care existing, then every strain of working in a job and earning money becomes more meaningful.On the other hand, think of the situation where career becomes more important. When one becomes career oriented, one's prime attention goes in satisfying the boss, working for long hours in the office or even on holidays to prove one's ambition, worth and commitment by giving one's best to the office but only secondary importance to family life. In such a life, there is every chance that the family relationships get strained, communication between spouses get bad, parent-children relationship deteriorates and so on.Ultimately, whatever purpose of having a job and earning money gets distorted and skewed because the original purpose (family life) goes on deteriorating on account of chasing a career! It is like a snake swallowing its own tail in order to satiate its hunger!So, family is more important than career.
What is scuba diving?

Apart from getting tanned at the sun kissed beaches, one can plunge in the deep waters and make some memories. Scuba diving in Goa is a splendid experience that you should embrace in case you are looking for excitement and activity. It is not quite the same as should be expected jumping as this includes utilization of legitimate gear, so it turns out to be anything but difficult to investigate the submerged world. The most vital component of this movement is its gear, which is a scuba breathing set containing an oxygen tank and a tube, joined to a mouthpiece, which enables you to inhale legitimately.
Is “scuba diving” the same as “diving”?
Diving is a broader term, and SCUBA Diving is one of its forms. When you say diving, it could be anything: sky diving, cliff diving or simply diving into a pool or free water body from a platform which is at a certain height. Diving can be performed with basic swimming skills and ability to hold one’s breath for a few seconds or up to a minute. On the other hand, SCUBA Diving is more of a professional dive into the water wherein you remain underwater longer than the usual dive. There’s a special suit designed for SCUBA Diving, plus the life support system that comprises Oxygen cylinder and other essentials. Most importantly, you would need an instructor, like those at Dive Career Centre, for experiencing SCUBA Diving in Cairns or anywhere else on the planet. Without an instructor, you may not be able to fully explore the aquatic life that’s breathing underwater. Visit - http://www.divecareercentre.com....
