I often tiptoe: when I brush my teeth, urinate in front of toilets, wait for buses, and so on. And I do walking on tiptoes for two thousand steps at least three times a week as my exercise. 

The effects? At 80, I dont stagger when I am walking, or need a cane or other help. Dear fellow old friends, give it a try.
