QUOTE: "Putting this together, it appears that goosebumps are part of a two-phased response to cold. In the first, the muscle below the skin is stimulated to form goosebumps. If this stimulation lasts long enough, the second phase kicks in, with the sympathetic nervous system calling for new hair growth and repairs for the old ones to be made in response to the cold."

I have been bald since my mid thirties. I am now going to shut myself in the freezer for 24 hours. If you don’t hear from me again, I hereby bequeathe my curly-haired remains to the local barber shop.
