I think that zombie apocalypse would be preferable to living and dying alone. Also someone may create a cure or we may ,,kill'' all the zombies and eventually life would return to normal.

The closest thing to having a business was when I created my art page on facebook...so probably not close at all.😛(also now that I make manga I also need to do several works. Writing story and making art). But that is also different from having a business.
