Are you the poker Matt Maroon? If so, I've been enjoying your writing for a very long time.

I definitely don't sit around doing nothing when I'm waiting for water to boil, but very often the water is still on the critical path (e.g., because I want the pasta to be done ASAP even if other things aren't done yet, or because it's on the critical path even if I can use all that time efficiently).
