Can you believe I got a sunburn purely in the SHADE!? A slight injury kept me away from outdoor activities except reading in the shade. So for some "light" reading I checked out about 1500 pages worth of Goebbels diaries from 1939-1945. They were kind of yellowed and fine print, so I used bright outdoor light, but kept religiously under shade of concrete overhang.
I started to get brown in a strange kind of tanning-bed omnidirectional way, where ever my swimming suit didn't cover. I wondered if this was UV being bent as they passed thru clouds or if it was from reflected UV. But then we had a cloudless day, and I got almost lobster red sitting in clearly defined shadows! It must be from reflection, or the scattering from particles in the air. I don't need any more skin sun damage, after volunteering to crew a sailboat one summer and too cheap to use sunblock lotion.
One useful item for this was internet radio with noise cancellation headphones. For a while there were jackhammers running and found I needed music with a hard beat to distract. Cuban music worked best (pandora cuban genre or spotify radio based on cuban masters playlist), but there was useable Goa world beat station possibly under tunin app. If it was quieter, I might play mellow ambient or chill jazz to distract, although if that is too sappy there are quite a few birdsong stations. I suppose it sounds odd that I listen to those next to ultrasound speakers intended to scare away boring local birds and their mess...
In one case I was reading about the invasion of Russia while the internet radio played birds and running creeks recorded in the Urals (Russia). You can tune in special Brazilian birds or more temperate ones such as from http://birdsongradio.com/radio-birdsong-listen.php .
When having a hard time sleeping (like with a sunburn) I sometimes tune in british comedy internet radio stations, such as found on xiialive app. There seem to be an atlantis.fm station and a ROK station with bbc skits about 50 years old. Today they kicked off a hilarious but unlikely recent comedy "HUT 33" satirizing the WW2 decoding boffins... I love the high strung violent Polish secretary who angrily mistakes brownie girl scouts as possible fascist brownshirts for example (as I read about the Polish invasion). I earlier mentioned (in temp forum?) the very funny Roman satire episode that I have now heard twice on those stations... was it on the Jimmy Edwards show?
