I would explore space..
Preferably black holes..
Should keep in entertained for a few million years

The same thing I do now.

Anything I want.

Rule over the non-immortals and carve a vast Empire.. seeing as though I couldn't die, it will have to happen eventually. I'll make the worlds national color purple (best color) and our emblem be the spider. Because spiders are crazy scary.

Maybe after a thousand years or so we expand to outer space and start looking at other planets to invade.

.. wow this thread made a nice book idea.

I'd try to kill myself

And after you were done trying to kill yourself?

Conquer Earth.

i would explore the deepest parts of the ocean and space
after that? come back to earth and a be a super hero

Will I continue to age, or be fixed in a certain state? If so, what age will I appear to be?
