I enjoy trying different activities in areas that interest me.  I also enjoy sampling new ideas that again, are of interest to me.  As I get older, I find I'm somewhat more willing to try something new because "What that heck, who cares anyway?"  Age seems to give a sort of liberation to constraints I had placed on myself years ago.  I do still step back from some situations, but overall, I believe I am much more open to newness than even a few years ago.   I find it really doesn't matter to most people what I think, do or feel so I might as well participate in as many pleasant activities as possible.
