I was an athlete in high school (ran the mile with excellent time on the track team and also participated in wrestling and weight training.) I continued weight training off and on through my 20s but had developed an alcohol addiction drinking up to a case of beer a day from my mid 30s and most of my 40s and did little to no exercise.

During that time I went from a very muscular 220 lbs to my current obese weight of nearly 300lbs. And I just turned 50 and have limited balance, and cannot even run a mile, let in contrast to being able to run that distance in five minutes, give or take. Also I am weak in the gym.
