My desire to be one of the strongest and healthiest 50 year old's around. Looking good will be a side effect. I got 1 year to go, as I just turned 49.
On my 40th birthday, I had a major Epiphany and began my 10 year journey. I quit smoking, drinking, and went gluten free all on the same day cold turkey and have not looked back.
I have already reached the health goal, as I was told by an internal medicine specialist last summer that I am the healthiest person they have ever tested on a cellular level. He said he wished he had my health, which is priceless because it was the equivalent of a healthy 25 year old. Living to a 100+ is a real possibility for me he said. (My eye issues are unrelated)
The journey won't end at 50 of course, but it will be a major milestone that I am so looking forward to.
