It's sad that I only seem to learn about artists of this caliber after tragedy has befallen them.

Alzheimer's in particular is a pretty nasty thing to succumb to. My grandmother had it and towards the end it got so bad that my sister and I couldn't even stomach going to see her. She was just a shell of who she used to be and as her body followed it became painful to see. I've recently started hearing Alzheimer's get referred to as type 3 diabetes, so take this as your reminder to take care to keep your nutrition in order and eat real food and fast once in a while. It's worth it to keep your mind intact.
