I think I'm addicted to endorphins. High on life. I've been going to the gym two and three times a week. Running. Flat out. In a little under two months, I have lost close to 20 pounds. I can now run almost 4 miles in half an hour.
Did you know that Webster defines endorphins as "any of a group of peptide hormones that bind to opiate receptors and are found mainly in the brain"?
I guess that makes me an opium junkie.
