My mind? No. Duplicating your mind into a computer seems like a good idea, except it just creates a copy that gets to run around. The me that's living inside this meat prison is still right where it's always been, but now you have to watch some youthful interloper running around with your bank account.
My brain though? Assuming it's a well-tested procedure, sure! That's basically my essence, and if I can keep that while getting rid of these fragile bits, I'd do it.
Honestly though, I'd settle for just replacing my entire digestive system. That seems to be the thing that breaks down and causes problems, not to mention it's a major vector for illness. I'd live with a metal digestion or photosynthesis or whatever if I could.
