Useful waiting time
Am sitting at my computer doing some citizen science as I wait for a delivery.
This is quite an easy project transcribing cards of bird observations taken in 1970's /80s.
If you haven't heard of 'Zooniverse' look it up. A way for using small chunks of time for the benefit of all of us. Most subjects anyone could be interested in are available over the months and years. I have looked at documents from Shakespeare's time, weather records in the C19th in Scotland and Europe, photos of animals on the African plains, Humphrey Davey's notebooks ( hard to read his writing! ) - now birds. Do as much or as little as you like, all efforts are appreciated and there is help and others on the same project to chat to.
