Good, good, good, uh-oh.

Cool to warm Spring day: Good.
Bicycling around town: Good.
Open wifi various places around town: Good.
Feeling heat of the sun on the back of my neck after sitting down at home: Uh oh.

Hopefully the UV dose wasn't all that high, but I think I just got that "Use sunscreen if you go out for more than a couple minutes in daylight" warning. I don't have to deal with emissions from nearby fusion reactors at night...
