I'm in bed by ten. I have two kids--just babies really--and I wouldn't have time to help with them if I went to the gym after work. I'm there when they open the doors at 5:30 and run and lift for 45 minutes. Then I dash home and get cleaned up and leave for work at 6:45. That leaves a few minutes to feed at least one baby.

It's pretty hectic but you never really have time to question what you're doing. By the time you do, it's become habit and you would be really cranky if you didn't get to the gym.

We're all really well trained apes, I think.
