Hmmm... I doubt you could do that while dead, as all your brain cells and neurose connections would be dead too.

But it is true that if you start up a habit, it's difficult to break it. For instance, I once faked a posh accent at school just for a laugh... and all my friends started doing it as well... we kept it up for several days, and now I actually find it hard not to speak posh when I'm with my friends.
