I'm only 23 and I have a ton of vericose veins on the backs of my thighs. I don't get it! I have always been active. Always played sports and my field work involves me hiking all day and running around the lab. So it's not like I just sit on my bum all day and I've always been told that's the reason you get them is from being overweight or "lazy". I'm at my goal weight, have never been obese or anything. I am actually pretty muscular: I say I have man legs. I can leg press about 350-400 without trying. So it's not like I fit the model of what supposedly causes them. But they're so gross! I hate them! And I don't know why I have them so friggen young! ARGH!
