Ya, like everyone said, you have to be sure and warm up well, and it will take longer to heal, but you'll be fine. I'm 34, and I'd say I'm bretty much at the median age for our school. I have minor injuries all of the time, jammed toes, fingers, etc. That's just the nature of the beast. Every once in a while, I'll take a week and let myself heal. I'll still go to class, but I'll just take notes and watch the sparring, that way I'm still getting some exposure to new techniques, but I'm not exacerbating any injuries.
Also, watch out for N00bs! Unfortunately, I think the recent proliferation of MMA in prime-time media has drawn out a lot of wanna-be-tough-guys out of the woodwork. They usually come to a few classes, get tired of getting tapped by 150lb blue-belts and quit. But while they're there, they all have to try to prove how tough they are, so they'll flail around ("spaz") and are completely uncontrolled, so you have to watch out for them, especially the big ones. I get 10x more cuts and bruises from those guys than from the regulars. (Mostly from them just flailing around) I had my ACL torn by a guy who was not in control and didn't know what he was doing and accidentally heel hooked me and rolled over hard, popping my knee before I could tap (even if I would have tapped, he couldn't have stopped his momentum in time to release pressure.)
I used to take it easy on new guys and mostly just work position... but after that, I don't f-around. I make sure they are in a position where they can't hurt me, then let them try to esape. I don't go for the quick tap, because that doesn't do anyone any good, but I don't give them any space either. If they get cocky, or too amped up, I'll go for the insta-tap or something really embarassing, and hard to get out of like a crucifix-to-choke/armbar.
Anyway, sorry to go off on a tangent there, but the point was, avoid new guys until you can get a feel for how they roll and you'll avoid a lot of injuries.
NOTE TO NEW GUYS READING THIS: Don't spaz and flail around when you roll, it will just make the guy that's about to submit you mad before he cranks it... think about it
