I lost my last grandparent last year, the only one I ever met (the others where dead when I was born), to Alzeimer's.
The grandmother I mentioned, seemingly last year, too. Two grandfathers were lost by cancer.
One grandmother is still living, though, and I don't expect her to die soon, she's simply too "earthbound" to do that. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
