I live on O’ahu. We recently observed the 50th anniversary of the first voyage of Hokule’ia which is the first voyaging canoe built and navigated in the traditional ways, which was sailed from O’ahu to Tahiti and is still active, currently on a worldwide voyage. My kids got to go on board when it was docked as part of their school and there’s been lots of stuff available here about traditional navigation. It’s all truly amazing stuff. I chaperoned a field trip last year where we got to sit with one of the former crew members and it was like meeting an astronaut. Their descriptions of being in the middle of the ocean among the stars on that traditional ship is just breathtaking.

Someone on Lemmy wrote, a little over a year ago I think, that lead ossifies in the bones and then gets released into the blood as bones soften with age. This then affects the brain and might explain why older people have seemingly sudden personality changes. I think about this often.
