While at a dog park one day recently....a friend remarks to me..."Well, I had a group of friends...make the "mistake" of going out together...and gosh...guess what...They all got sick?
So, Like the common flu....it spreads to others, some get sick, all get better...allow me to add two unintentional benefits to my argument....those who got sick, got better...AND they now carry the anti-bodies that can actually cure those rare few who do get seriously sick.
