I wear one as I had a kidney transplant about 6 years ago and it is important the drugs I take are continued if I have an accident. I wore one for the 5 years I was on dialysis as well. But I've always preferred to wear it round my neck rather than on my wrist, so it is effectively invisible unless someone actually undresses me, which sadly rarely happens.

Ely, tell your mother it's worth the wait, the joy is boundless.
