yesterday helped a desperate woman change her flat tire. her jack broke & since every passing car treated her like a mental case & because I carry two jacks, it was an easy assist. she had pulled into an office park to change her tire but when she had problems w/ her jack she had to walk out to the roadway to ask for help. since no one could see her car, she just looked strange approaching passing cars. I could never forgive myself for not turning around to investigate. was prepared to call 911 but I needed an address anyway. she had a cell phone but didn't want the police to tow her car. she did most of the work but I did participate. was on the way home from the gym where I was testing the shoulder but mostly doing leg & abs stuff. so yesterday was a big day for the shoulder. was careful, but used it more than I was planning. I've added Glucosamine Chondroitin back in to my daily supplements
