I don't quite measure up to your standards of gravitas, but since getting married a few years ago I've put on 20kg... and its serious ****...
4 years ago I used to surf, run and cycle...(pre-marriage ahem) 6 weeks ago I was lucky if I could make it to the remote control without wheezing...
Serious serious ****... so I started walking (screw running since I couldn't actually do it).... 6 weeks later I'm still a fat b*stard... but at least I've made a start...
The moral of the story?
Get test-tos-ter-on jab in the buttocks and all the excess baggage will fall off but your nuts will go from grapes to raisins.
