Melody -

My veins have always been very prominent - first I think - like Mrs. D. said - I'm a pale faced Canadian and so you can literally just look at my arms and see them all..... Also, I'm thin - but I dont know if that has anything to do with it or not...

I can tell you - when I used to be able to do heavy exercise, especially putting pressure on my arms (like motorcrossing and stuff) the veins stuck way out (and I think that happens when anyone is exercising or cleaning or whatever - maybe ask Allen if it happens to him at the gym?)...

Never hurt me - but yes, I think they do vary depending on stress on my arms.......
