Are there any activities you loved as a child, and continue to do on a regular basis?

I’m just asking because I love to color. Sure, I’ve graduated to the “adult coloring book”, but nonetheless, to relax and unwind, I color. I loved it as a child, and I continue to it on a fairly regular basis. How about you? Just curious as to what “childish” things we are still doing as adults. And when I say child, I mean under the age of 10.
