They say that it's better to start something new when you're young to avoid humiliation. As an adult, you're not expected to learn new stuff: languages, sports, art, etc. Your skillsets are permanent. While that may be true, it doesn't hurt to shake up the system to remind yourself that you're still alive.

Technology turned us all into foxes instead of hedgehogs. We might be amafessionals, but we're far more capable of creative pursuits than before. It turns out all we needed was a widget, the Internet's connectedness, and a little bit of curiosity.
We've been conditioned to avoid error and taught to keep doing what we're good at. But learning to do more stuff keep things more interesting.
