My Awesome, Strong Kid

I always forget and take videos sideways on my cell phone, so crane your head to the side and watch my friggin' awesome kid scale up to the top of this 12-15 foot swing set in like 2 seconds!  He is only 7!  I could never do stuff like this, even in my most grandiose gym class fantasies.   After that he did the monkey bars, first with both hands, then with one hand on each bar, swinging like a monkey.  Then we finished a really long bike ride, during which he whined the whole way.  Does that make any sense?  Anyways, I am way envious of my child's upper body strength.
