Reason #2... NOT to have kids:

They will show you how weak and pathetic you are. These two brothers are amazingly strong and flexible and obviously disciplined. (but two HOURS every morning!?) I just hope they're having a little time for fun kid stuff, too! Why doesn't their father show off his physical abilities...? Because the kids are definitely more capable of the "human flag" push ups and front slo-mo flips towards the camera. I would like to see updates in the next few years (aka: the Olympics).
