Leg Veins for Miles
If you’ve never seen Thor in Shorts, well, here you are. This is the left thigh, knee, and calf of the god of thunder, and it looks like there are literal lightning bolts running up and down his limb. With veins that thick, you’d think that optimal blood flow wouldn’t be a problem.
In reality, this is a picture of a professional sprinter’s leg. It was taken almost immediately after an intense workout session that would make any normal human being pass out of exhaustion. It looks freaky, to say the least, but you have to admire the blood vessel network.
