Luckily my leg hair kind of peters out around my pelvic region so if I did shave it wouldn't be difficult to know where to stop. As I mentioned upthread I did try it once and it generated so much hair that I wished I hadn't started. However I did crash that day, got crowded by a car on a French Alpine descent, skidded on gravel and slid over the edge falling several feet down a rocky slope before coming to rest against a small tree so the resulting injuries were easy to clean and dress.
