Sure, why not? I have a lot of free time on my hands where I'm too lazy to play games and I've already done all the work I possibly can...
If I had to come up with a character I'd go with-
Age: Jean Twenty-six.
Summary: Basically just your average, absolutely worthless human being.
Except he was in his final year of studying for a career in medicine before the apocalypse began and he would've been very very good at his job as a high class doctor. But he's actually very pleased because his parents wanted him to do medicine and he just wanted to open a tea shop...But otherwise, he's just chill and really doesn't worry about much.
A bit of a dick sometimes though.
Flaws: Can't run very fast, but he can run for a fair while; not very agile or athletic, but pretty tough.
And really really shit at maths.
Mental Status: A bit of a clean freak and really really hates eating scrambled eggs.
Suffers mental breakdowns when exposed to complex mathematics.
