I basically say....HAVE AT IT!!
I'm not going to be using it anymore! Seriously, if my kidneys are in good working order, my sister gets first dibs on those as she is waiting for a kidney transplant. If someone one needs something from my body after I'm gone and they can use it, then by all means use it. If studying my dented ticker is going to benefit someone else, then go for it....like I said, I won't be using it anymore.
