Ask HN: What hobby do you enjoy that's not at all related to SWE/IT/CS?

Photography. For me it offers a great mix of technical skill development, gadgets with satisfying knobs, software challenges in editing and workflow, ability to do it anywhere and anytime even as a busy professional and parent.

Bass fishing

Bicycle Riding (Mountain bike, Road bike, and BMX)

Weightlifting (in the colloquial sense, not the Olympic sport specifically)

Tinkering with old cars
