Yeah old thread indeed - took me a bit to notice, I was thinkin' Wow some folks I haven't seen here in awhile!
In all seriousness, I am a big advocate of donating your body "to science", for all you guys that don't want alot (or any) $$ spent and don't care what is done, give it some serious thought. They can't pay you (er, the family).... turns out that's illegal (HA!)... but in many cases the receiving agency will cover the costs.
There are lots of options for what you can do, aside from organ donation, in some cases still even after organs harvested.
When I was at Wake Forest, our dept. handled the Gross Anatomy lab that served the Medical School. They had (former) people coming in in all kinds of conditions. It really is a great opportunity for students to learn about how the body works/everything is connected... and I like the idea of Med students learning to use a scalpel on a dead guy before practicing on me!
One cool fact, they extract the brains, and they are used by Neuroscience grad students to take to "demonstrations" at local schools (I started a club that did this) to talk about anatomy, brain facts etc. Nothing funnier than a 10-year old's face when you reach into a bucket and pull out a real human brain!
I'll be donated for sure.
