I'm in Ukraine frequently got a lot of reasons, e.g delivering a donated 4x4 recently, and getting institutions there to use OpenTimestamps. Also, I like Ukraine. It's a nice, cheap, libertarian county with low taxes, low crime, and good weather (I like snow). If not for Russia trying to kill everyone it'd be awesome.

I've risked my life doing a lot of dangerous things for fun. Some risk for something worthwhile is perfectly acceptable.
