FYI, I loved calculus, although the TI calculator in the video did not exist when I took it.

“Johndevous” in Roseville
Some of colgaffneyis members are at John O’s, down near Winona for a project weekend (“Johndevous”). John has a very impressive shop and invited anybody in the group to come down there to work on their own camp projects. I decided not to go. I have a shop of my own. John’s shop is better than mine, but not enough better to offset the hassle of driving to Winona and camping there. Also, here I do not have to share the tools.

New study in The FASEB Journal shows how and why molecules released from burning incense in religious ceremonies alleviate anxiety and depression

More on clothing of the common people
From kass_rants:
You see, in the medieval and Renaissance periods, people had to make use of every scrap of fabric. Labour was cheap and fabric was expensive. In the early modern period that followed, wealthy people wore lace collars that would equate in price to an estate in Ireland. So you see where I’m going with this. If you had an expensive piece of brocade, it probably cost more than your house. So when you made something from it, you pieced it and turned it and used every last scrap.
Modern dressmaking techniques waste a lot of fabric. They are engineered for speed of sewing. In the periods we study, speed was not as important and conservation of fabric.

Another ice pack
For the second time in 48 hours I am wearing an ice pack. The nurse at the Red Cross decided to try a different vein for apheresis (platelet donation). It did not work. Two other nurses tried to adjust it. No joy. In fact, considerable pain. They had to unplug me.
