From the age of 16-19, I went to the gym 6 days a week, ate and slept well and was in excellent physical fitness.
Now I am 24, haven't worked out in 5 years, and have a terrible sleeping pattern (4-7 hours a night), and eat even worse! My body is gone well and truly to seed, but despite all this, I am a lot stronger physically than all of my friends, even those who exercise regularly.
Why is this?
