Great genetics and work ethic obviously. Do you find it tough to get the meals in as well as hitting the gym with kids? Please don't tell me you eat whatever you want and get to the gym when you can, cuz if thats true i'm gonna give up weightlifting. 
No, I use to be able to do that when I was younger and never held much body fat. Now, I have to watch what I eat when I want to get my body fat down like I had it in Bangkok. As far as the meals I'm in a pretty good situation. I'm divorced and my boys stay with my X. I've been working as a defense contractor overseas since 1995 and during that time I have been lucky enough to get a lot of my meals on base and for free. (all you can eat) I'll attach a pic of when I worked in Kosovo. I was the Manager for the employees operating all the military Fitness and Recreation centers in the country. I had 24 hrs access to all the fitness centers as well as all you could eat dining facilities, some open 24/7. All I wanted to do is eat and train. Imagine how much size you can pack on when you eat as much good food as you want and can train as often as you'd like, pretty much anytime you like. It was like a dream come true. I also ran the military facilities in Kuwait and Southern Iraq for several years. So, pretty much no problem with food and opportunity to train. I'm currently working on a base in Iraq where I have access to all the food I want and there are several nice gyms on base to train. Although the dining facilities aren't 24hrs they do serve breakfast, lunch, dinner and midnight chow. I usually hit them all. (all you can eat at no charge)

attached pic was taken back in 2001.
