Will anywhere mail me some information about living wills or anything so my grandmother can read it? She's not into technology.

This site is for caregiver support. It does not have information to mail out. Your best bet is to use Google to find what you want then print it out. To start your hunt look for elder law attorney websites in your state. You likely will find some pdf's of brochures with what you want. Or setup a meeting with an elder law attorney to begin to get everything in place.
