Yes, true. I'm *really* old at almost 60. And I've found that you can't keep up with everything; but you don't have to. Some things go away before you get a chance to feel foolish for not using them (like MySpace, and just about anything that Microsoft makes:-)).
In my case, I'm still using Emacs/gcc/gdb to write C code where I work. But I've ported my old open-source project to Android using Eclipse with Java, and my Android phone is my main internet and entertainment device when I travel. And I'm an avid Facebook user, but don't feel I'm missing anything by avoiding Twitter.
After a while, you'll develop a better sense of whether something is a fad (or marketing ploy), or a useful development worth pursuing.
