If death is inevitable, why bother?

Why do we feel compelled to live life like it has a purpose? Okay, death could count as purpose, but why bother adhering to rules and being 'good' if our bodies are just going to rot in the ground?

(I probably sound like an idiot to the philosophers out there but I am intrigued about the responses.)


*cautiously submits thread*

If you are here to reply with the fact that I am being pessimistic, etc...don't worry, you don't have to waste a post as a few already have done it.

I purely created this thread because I was curious about people's attitudes towards life, not because I feel that there is no point to life or to bring anyone down.
