As a bullheaded bio-person, I wonder: What can nanotech do for life-extension today? (i.e. not within a "decade" of methodological refinement?)
I would especially like to address all those of you with an actual nanotech engineering background out there: Imagine you had a small grant, a lab and some infrastructure. You want to do some nano-based life extension work (in the context of cell biology if you like), starting tomorrow. What would you do?
