Arnold Schwarzenegger went for a bike ride with his daughter. He's 73 years old? When did that happen? And normally I cut celebrity children out of these pictures but she's 29 years old and not 13 like I originally thought. Maybe it's all that Austrian blood that makes them both look so young. Arnold would have been born in 1947. In Austria. Right after WWII. I'm not hinting at anything about his genetics, but maybe I am (I am). You know what was going on over there during that time? I think the evidence speaks for itself doesn't it freund.
