My Hobbies, My Free Time
Programming
Because let's be honest, programming is just solving very cool puzzles!
Sailing
Since I was a child, and nowadays also as the Skipper aboard charter yachts during vacation.
Music
Just listening to it, or playing music myself. Anything music related is just beautiful :)
Chess
Mostly on the open source chess platform Lichess, where I achieved a rating of 1700.
