I’ve also worked hard since I was twelve (now I’m 48) and my hands and arms have huge veins sticking up if I’m not off work for a day or two. BP is fine though since I went from 162 lbs to 113 lbs in 5 months. But, the parts I work with have sharp flash (plastics factory) and I’ll get those red slashes that make some people think it’s an Aids thing. NO, hubby and I have been faithful to each other for 20 years, this is just thin skin that has gotten thinner. And today I got the scrape over one of the veins and bled like crazy even though it was the most miniscule of nicks. Had blood dripping and curling around my wrist, for heaven’s sake.
