I knew I wanted considerable education so that I wouldn't have to work as hard as my parents.
Nitric oxide was known for destroying things.
There are very few things in the body that nitric oxide doesn't regulate.
Grade school, middle school and high school were relatively easy for me, and with little studying, I was an honor student every semester, graduating 5th in my high school class.
I am not surprised that other gases may participate in cellular signaling and regulation. Our early work with nitric oxide was just the beginning. I'm sure more will be discovered.
