(female) why would the hair on my legs just stop growing at my age of 58?
Our bodies do change with age. In women, after menopause, there are lots of hormone changes and some of these may impact your leg hair, as would the genetics you inherited. Count your blessings, you don’t have to shave your legs anymore if you are an American (culture pushes shaved legs), but in some European countries, hairy legs are better, so there you would be an unfortunate woman. I think if you could find the cause of your problem, I think that I could sell it in North America and we can make millions together.
