Are we all just living in delusion?

I mean seriously, 100 years from now, i guarantee everybody on this page dead?

So what if you good looking, so what if you got money, so what if you have nice possessions & fame.....in 100 years we will be replaced by a generation in which 1% gives a fuck about what we did or said?

This world, people get caught up in all these small issues, when really we dont focus on what happens after we die?
