I love this bit (in a sick kind of way)! I've said to friends & associates
for a long while now, that I'd rather live on as Davros (freaky shrivelled
hideous puppet guy in an automated wheelchair, super bad guy from Doctor
Who), than die a natural death; I'd even prefer it to cryo (I like to watch
history go by, thanks very much). Given that really good regenerative
techniques (reversing aging, using cloned bits, nanotech repair) or better
than decent alternatives (uploading, lots of possibilities for interesting
replacement for human bodies) are just around the corner (certainly in the
next 100 years something should pop up), then hanging on at all costs (eg:
as a head on a paralysed body (yuk!)) is a really good idea for us
life-enthusiasts (pro-lifers? ha ha).
So now I really can become Davros. I'm getting the 'chair and the funky
headset built now!
