I'm 55, I have no problem learning something new if I am interested in it, and I think that is the key. Some people just seem to lose interest in new things as they get older, sometimes as young as 40, I have seen. Once you lose interest in new things it's very hard to learn new things. For some people it seems there is a certain comfort and security in only doing things you know, for others it is the opposite - same same is boring and new things are interesting. I see collegues, some more than a decade younger than me, setting in their ways, and the biggest predictor I notice is music tastes. Once they start closing off and lacking interest in any new music, that's the beginning of the stopping of growing (and starting of dying) in general. Make a point to listen to new music. Also, children keep you young, if you have them take some time to listen to their music and talk to them about the trends in their world and keep familiar with their jargon. That will also stop you getting old before your time.
