This may be off the subject as far as conditions---a couple of years ago my cousin Liz received stem cell treatment in Beijing, China to treat her ALS (not allowed in the states). She said after the treatment she felt better but passed away a little over a year afterwards. What is really strange is her younger brother during that 1.5 years, also caught ALS and died less than 6 months after his sisters death. I'm not sure stem cell treatment helped or not. She lived as long as the American doctor predicted regardless. I believe my cousins were contaminated as children. Their father was an officer in the military who moved the family all over the globe their entire lives, many military bases, several in 3rd world countries. Liz also served in the Army after college.
