I'm 74 years old and am starting to limp. Went to the doctor today and he suggested, less strenuous work, better eating habits, much more rest and lean against something when standing idle. My thoughts are, maybe the time for me to become a fireman. I am an engineer, have a lifted truck already, think I may be a shoo in to drive the big red truck and pull the string that rings the bell. Any constructive thoughts would be appreciated. :thumbsup
