I’m turning 56 on Dec. 3 and still thinking like a 25 year old. Doc’s don’t agree with silly talk of hip replacement , and maybe a shoulder replacement due to injuries while a Volunteer Fire Fighter and EMR.I have found that if you surround yourself with young people ( I’m now a Security Supervisor in a Casino ) It helps to keep you moving and willing to try the extra mile. Along with following the advice of a good doctor.I try to walk 2-4 miles a day and do light weights 3 days a week.It’s never kept me from hunting the back country of Ontario.I also dropped 70 lbs in two years.
