I'm an organ donor, and I'd gladly donate my body to science. My body is just a vessel for my mind, and doesn't define who I am, just what I look like. And it helps me move around, talk, see, eat, drink wine....etc etc ;)
Once I'm dead I really won't have the capability to care anyway, so no big deal to me.
Since I am HIV+ it is automatically cooties in the donor department. I will probably leave my body to science. But it will have to be under the condition that nobody has to pay a dime for this to happen.
Our bodies (my husband and I) will be donated to Science upon our demise, after our usable organs are removed. What’s left will be cremated. The same goes for our children until they can decide for themselves. I found a company called Anatomy Gifts Registry that does this (though I am still in the process of checking them out completely). There will be no burials or funerals. I think we have enough waste (landfills and bone-yards), I try not to contribute to their overpopulation. If some one in our families wants something to fawn upon (i.e. tombstone) when we're gone they have been instructed to plant a tree or donate to one of our favorite charities.
Personally, I'd like every molecule of my body to be used for something. I want to be recycled. Donate my organs. All of 'em. Give whatever's left to science to be studied somehow. Make a bird feeder out of my skull and a window garden with my rib cage. Any left over gristle or whatnot, compost it and feed me to the earth. Be creative with it.

"Yes, it's my old friend Seth..."
I'm an organ donor first and whatever is left goes to science. (Currently a regular blood donor and on the bone marrow registry and all for sharing whatever can be used after I'm done with it!) Man and if I had a friend who would appreciate an Andrea ash tray and none of the above wanted something that would lend itself to it I'd be all for that too! Ha! After that, worst case burn what's left.
I hate the idea of my loved ones being taken advantage of because they're grieving. I really like the idea of planting a tree instead of a tombstone or some other. So much less morbid. I've talked it through with my family so that I know that they're comfortable with these decisions and are completely clear on my wishes.
