I never been skinny, but I was quite slim up to my 40's
I managed to continue playing rugby until the age of 39
I've lost nearly 2 stones and now have the same 34" waistline I had at 35
The downside is that I'm not able to continue with my daily cycling.
I now walk at least 2 hours every day. Sometimes more.
Here in the city I get more tempted to eat-out. I must put a brake on that habit soon
For me life is good, I'm learning to live with those things that used to irk me.
