Sports & education goes parallel in life
A person good at education is good at any sports like In-door or Outdoor games
A person who works hard can be good at sports if trained, even the student who is physically impaired if mastered the technique of sports skills can compete in sports for all.
Every countries follow different methods of training & education for students
If countries select individual for the sports & a different country follow the selection of talent while in need.
Few countries follow the method of Gene selection If father is a sports person son will be preferred
Selection has different method however success is to person who has trained hard & deserves for his effort.
Mean we also loose best talent without representing on any events or competition
Keep trying until you success
