Personally, if you want a centuries old fellow and are interested in exploring the way that a person might become jaded or warped mentally by the passing of nations, friends, and time, I think you should. It's a deep concept and one that would be interesting to explore.
Do they value life any more?
Are friends something they even try to make?
But, I wouldn't make it a primary talking or even role-playing point. Why would they bring that up to anyone other than a close person after all? Just walking around talking that way seems like a real easy way to end up in a crazy house or burned at a stake ic'ly. So maybe they never talk about it.
Ultimately it's your character and if you want to do it and you don't shove it in people's face or bring it up in character very often cause it would be potentially dangerous, I think you have some real opportunity for some very thought provoking character development and exploration.
