Ever heard of a 'friendly bacteria'?
Recently a bacteria living in the soil was unearthed. When it was investigated, researchers discovered that it caused a substance to be secreted in the body. Imagine their surprise when it was found to be serotonin, one of the 'happy' hormones which make us feel good.
We always knew it was good to get your hands dirty when you garden. Now we know why. Man came into being in a garden and needs to return to live a meaningful life, producing fruits of the soil.
