Why don't people live longer than we do?
user
Well, living longer means you'll get more time to be alive, and we can only assume that people want to do things in that time.  And most people who are alive want to have fun, and it doesn't seem like this is possible without illness, or at least at least potential illness.

Some other animals live longer than we do?

Yes, so-called "primates" are an example, as are large vertebrates in general, some fish and maybe even some plants.  So other animals also want to have fun, at least so far as we can tell, and they also get sick.

I don't think these other animals live longer than us.

Can you explain why you don't think so?  Or what makes you think so?

Perhaps you can explain what you mean.  It sounds like you're saying that "what we see is not the whole story".
