I broke my two left toes 15 years ago, the joints ended up the size of golfballs. Could never wear my cowboy boot ever. My knees and both hands were bad too. Finally on March 1st 2013 I was going to buy some SierraSil and to wear my boot by 20th of March for my birthday. March 5th 2013 I was wearing my boots and back to my oil paintings. Thank you, Thank you SierraSil. Keep up the good science. Love you all PS I am 61 and running circles around the young ones.
