I guess i'm a bit in the mood of opening up old forgotten topics.
Well i'm from India and answering Charlies' question directly, sports is NOT an option in the country.It is not looke upon as something respectable. There's no focus whatsoever in sport. In fact the word sport doesnt even exist in the common Indian's dictionary. If you ever choose to take up sport as a career here in India, you'll be dead long before you know it, unless of course you happen to be a cricketer, which brings me to another good point made in here that it's the most popular sport in the particular country which sucks up the majority of the sports persons.
Cricket is a big bad bully in the country. Everyone from the wannabe Sachin Tendulakars to slum dwelling undernourished chilren, aspire to be a cricketer in this country. Why? Because cricket spells instant transformation into a demi god and name and fortune. The Indian cricket board,BCCI, is supposedly richer than the world governing body of cricket, ICC.
This where all the world of difference in exceling at particualr sport comes up. How your country views your chosen sport, whether there is a gurantee of a future, whether your country even respects sports, it all makes a difference.
I personally know a brilliantly gifted athlete, his 100m was 10.73 at 17 years of age and long jump 7.52metre. He's never trained . NEVER. He's never done plyometrics. Never even hit the weight room. He's a complete natural. If he were to put in the effort which athletes normally do i wouldn't be surprised if he hit World Record times upon maturing.
But he'll never practise and train simply because there is no future. A country like ours with a billion plus population has actually surplus talent. But it's never harnessed. It's never encouraged. Whether by parents, school,college, government. Nothing.
For all the talk of India becoming a superpower, i say it's all a load of crap. China yes,possible. India no never. Sports and physical prowess has never been a part of our history,never will be, That's why you'll find Indians in highly skilled professions of doctors,surgeons,scientists etc but never as sportspersons.
China on the other hand will continue to excel because its history has always emphasised a balance of both physical and mental powers.
