When you eat a #balanceddiet that is rich in #iron, it stimulates #hemoglobin production. It also helps transport #oxygen to other #bodycells. Hemoglobin compensates for any loss of #blood resulting from internal or external injuries. #Women, who lose blood during #menstruation, should make sure to eat plenty of #ironrichfoods to avoid #anemia during and after their monthly cycles. However, iron is an #essentialelement for men as well. #traceminerals

While oxygen, carbon, hydrogen, and nitrogen make up 96% of most human bodies, my body is composed of sulfur, argon, calcium, and samarium.

Edited: Gramps solved it for me in an unusual way.

Hey #genealogy community, before I jump into a coding project, maybe one of you has a solution. Open to free and to inexpensive options.

I want to pull certain information out of note fields, using a GEDCOM file. But the desired information is often split across 2-3 lines and needs to be reconstituted.

I tried #Gramps but it emits no notes to the CSV for me. I Also tried #oxygen and it emits the notes, but without any line breaks, so I would need to write code to parse them.

My thought is to run through the GEDCOM, find the phrase that indicates what I am looking for and then reconstitute that line with the following information and write that out as a single line, ignoring everything else.

Other ideas for tools that write out files that include notes as entered, not split or joined?

Antarctica has a waterfall that looks like it's bleeding. It's called Blood Falls, and the striking red color comes from iron-rich water seeping out of a glacier. When the iron-rich water comes into contact with oxygen, it rusts, giving the water its creepy blood-like appearance.

As a precaution to help prevent decompression sickness (the bends) U-2 spy plane pilots need to breathe pure oxygen for an hour before flying to purge nitrogen from their bodies.

Prochlorococcus is the smallest photosynthetic organism on Earth, and produces up to 20% of the oxygen in our entire biosphere.

The Perseverance rover's 'MOXIE' instrument creates 10g of breathable oxygen per hour from Martian air.

Is #Rust what you get when you document your #Metal APIs using #Oxygen?

What happens if you instead use #Doxygen?
