Madara?

How old is that mofo? Can't find anything on it. He must be 30+...maybe? He had to be atleast twenty by the time he faught Hashirama, and then 12 years after that was Part I, and then 3 years later was Part II... So I'm guessing atleast 35, because at the time of Konoha's founding he looked pretty mature, so he might even be in his 40's.

Any info on that?

No idea. I think the 40+ thing sounds alright. But I dunno about it.
