I found it surprising that there was more than 90 Italian governments in her lifetime. You learn something new every day.
The last living link to the 1800's is no more. This lady lived in parts of THREE centuries. I've made it through two, I am certain I won't make it three. Somewhere on earth is an 18 year old, on snapchat being a millennial tard that will outlive everyone else in their generation. Look at your local High school seniors. Odds are some of them, at least a few, will live to see 2200AD.
What happens when we have a thorough grasp of the "longevity" expression? Are my own crappy cells of presumably poor longevity still superior (in application to me) to foreign cells with better genes? Edit: I realize (not fully) how complex of a question that is, just ruminating. Carry on.
It's an interesting question. My bet is that it will be easier to improve on yours rather than get your body to accept and benefit from another's long term. Will all humanity converge to be the same long lived genetic individual? Eeek. Probably not the most 'anti-fragile' strategy. Btw 'anti-fragile' is a very dumb term.
No problem. I'm done with typical conventions. ɔ ᴉ ʇ ǝ ɯ ǝ ɯ But we haven't the resources for everybody to live forever : /
