I hope this opens your eyes to really work hard at losing the weight you wanna lose. I am not the smallest guy by no means, but if I was having the same problems as you at our age my arse would be hittin the gym everyday!!!! I would put huntin on the backburner!!
Gd Luck man, hope it all comes together for ya!!!
