Go look up Dick Hoyt beyond what I posted. He does TRIATHLONS with his son. Thats 3(5?)mi swim, 26mi run, and 100+mi bike ride. You will see how much his son loves it.
Yeah, I agree. I've seen that. The son clearly has way more understanding of the outside world than the expressionless 13 year girl who's mental age is of a 3 month old baby. Would a 3 month old baby enjoy that? You could get criminally charged if you did that with a 3 month old baby. Oh wait, it's amazing/heroic when you do it with a 13 year old with a 3 month mental maturity
