Yes the key is keep learning - unless you keep up you will end up on the scrap heap very quickly. I am not quite as old (45) and I still love learning new things, but it does take more effort than when I was younger.
>> but it does take more effort than when I was younger. Absolutely true, and it's also fair to say that I have to work harder now to remember things that I could recall effortlessly twenty years ago.

I know most developers couldn't work without the Internet these days, and that's doubly true for me…
