It pays to be dirty.

Gardening is much more than just a hobby—it’s a biological interaction with the Earth that changes your brain chemistry. There is a harmless, common bacterium found in soil called Mycobacterium vaccae. The Serotonin Boost: When you garden, you inhale this bacteria or it gets onto your skin. Research shows it stimulates a specific group of neurons in your brain to produce Serotonin—the "feel-good" chemical.Prozac of the Earth: Scientists have found that the effect of this soil bacteria on the brain is similar to antidepressant drugs like Prozac, but without any side effects.Brain Power: In studies (like those by the University of Bristol, England), mice exposed to this bacteria showed reduced anxiety and a significantly higher ability to learn new tasks. So folks, it is Spring. Time for gardening. Time to get dirty.

They say that cleanliness is next to Godliness. 😇 I’ve always scraped my fingernails along a bar of soap.

I have been a firearms cartridge hand loader for 56 years. About 30 years ago I started using surgical gloves to cut my hand cleaning chores completely. And while I no longer change the oil, filters and rotate the tires on my cars, I still do the maintenance on my John Deere garden tractor. The surgical gloves are a must have.
