If you are a volunteer it is an opioid addiction. Family and friends come first though volunteering in an inner-city school and at the Smithsonian are a high knowing you contribute to others while connecting to those outside your bubble and sparking a few synopses that have sat in the rocking chair. I volunteer teach biological lab science for an NGO to 5th gr inner-city students, Help a paleo biologist write a journal report and prep his 20-Myear amber. I mentor two beekeepers, (beekeeper for 19 years) and run 1/2 hour to an hour 7 days a week. Total milage for the past 47 years adds up to circling this perky little planet 4 + times. I write with lots of changes while enjoying the struggle and learning. My immediate goal is to devise a foldscope protocol for collecting environmental data that can be done by my 5th graders.

Blood on crystal violet stained slide. Red cells are small grey 6-micron dots. Deep red-violet blot in upper right is a white cell. Smaller blot is a b-cell. Sample stained with crystal violet. To push beyond the foldscope-eye limits try to team it with a high definition smart phone. A RBC is shaped like a mint lifesaver. The outer edge is thicker than the middle. When viewing with the smart phone zoom in to reveal the 2-micron edge. The normal RBC can be distinguished from an abnormal one. A WBC is about 24-microns, and depending on the shape you can make out the various WBCs, T-cells, and B-Cells. WBCs are about 1% of the total blood. The purpose of blood is to feed body cells and remove wastes while fighting off foreign viruses.
The study of blood is Hematology. a link is provided.
