I'm not an expert but I bet there are issues of scale here. We're men, not mice, after all.

There's another issue which is discussed in a scifi series called Altered Carbon. Presuming we could have a very long lifespan, imagine what that would do to people as far as careers and retirement planning. It would be a massive disaster.

A very long lifespan would be a headache, read somewhere years ago that our brain can only support 300 years in memory if kept healthy. If that is true I think we'd start forgetting things after 200 years. 300 years we would start sense the world aa if we were plants I suppose.
