How do you feel about the idea of living past your normal lifespan?

We're talking like living well past over 100 years. Was reading on transhumanism, where they were talking about expanding our average lifespans dramatically via genetic enhancements and super vaccines.

For me, I don't fancy living past my natural span. Every day is special since we don't know if tomorrows coming. Just being here today is a blessing in and of itself.

What do y'all think?
