Sports is not all about strength and power. Sports like Table tennis, Badminton, Shooting, Archery, Chess, Carrom, Golf and marathon don't require strength at all. There are many indoor sports too. Mental strength, endurance and alertness are also important factors in sports.
Being physically strong has nothing to do with being healthy. I think being intelligent is more important than being strong. Just look at West African Blacks, they are just stronger but their country sucks. I know East Asian are weaker but they are very smart. This is the reason East Asia is so progressive.
I don't lay so much importance in Sports. Staying healthy and active, both mentally and physically, is the most important thing. I'm myself a genetically inferior for sports (I'm Bengali Indian), but I believe my ethnicity is the smartest in India. I don't have any shame about my physical weakness. Being progressive and intelligent is our biggest priority in our life.
