alright here we go. sorry to change the topic, but you want it so here you are.
have you seen how much pro ski racers train? they train all year round, they train every part of their body so they are in pristine condition. Try racing a downhill going close to 90 MPH (or however insanley fast they ski now a days) and try standing up when your done. you will literally fall over because you are so damn tierd. Now think of doing that all day for training... Ski racing is a damn hard sport. Its not the same as skiing groomers all day. Downhill is nuts. People go by the gates at 80 MPH (again i dont know the exact speed, but when i raced i got clocked one time at 55 MPH in super g, so the pro ski racrers must be going wayyy faster). imagine hitting plastic with your arm going that fast, keeping your balane, then flying off a little knoll (or whaleback, whatever you call it) and landing 50 feet down the hill in mid turn with all of your weight and then some pushing down on your legs.
of course, like in the other thread (that i got shit on) old people with little atheltic ability and skill can ski. they suck at it but they can still ski. Old people with little athletic ability and skill can also play baseball, but it wont be near the level of pro baseball, just like the old skiers are nowhere near the level of pro skiers
