@tori32 I actually wear two small silver bracelets on my left wrist. One is flat, less than 1/4" wide, but has an imprinted design that I can feel. The other one is a simple Morse code bracelet that spells out "perseverance", and has the small beads and spacers. In the past I have carried an interesting small rock in my pocket that I can explore with my fingers.

Let's see what others tell us they use! Do you have a favorite one?
