Personally,when I hear people say "Don't expect me to change. I'm over 50. I'm set in my ways" I take it as a BS excuse to continue doing something or to get out of something.

I know someone that acts like a complete asshole,treats his wife like crap,does drugs all the time,misses work all the time,etc. and even though it causes major problems in his marriage he likes to use the excuse that he's "set in his ways" and he's too old to ever be different,too old to go get help or be helped.He says he can't change.I have called him on his BS because this same person that can't be expected to change plays video games,has a cell phone and all the latest devices,all things that require learning how to do,which is change and stepping out of old ways.But he can't learn how to not be an asshole,he thinks he shouldn't even be expected to change or try because he's over 50.

They're capable of change,it's just that they choose not to.Surely if they can catch up and keep up with the world today they can change just about anything if they're willing to learn and try.
