Also 36 here, and a day never goes by where I don't think about gaming. I play every day that it's feasible, currently most days.
I'm a console gamer for the main reason that the games I like to play - those that do something different or push the boundaries in certain ways - are on Nintendo platforms. As a previous poster mentioned, I'm generally bored of games that retread the same ground, which is often the case with a lot of first or third person games. I have a 360, too, and only recently got rid of my PS3. I have a bunch of old consoles, a good emulation PC, and also an arcade machine (Flicky, 1984). So I think it's safe to say I'll be gaming until health dictates otherwise.
My Dad introduced me to gaming with the Speccy. He's now 64, and still gaming. These days he's casual web games, board games and cards games only, as that fits best with his lifestyle. I expect he'll have just had a game of online pool or Uno when life shows him "game over".
