lol , You have many more years to be active and many more to lift if you live smart . E-2 levels have been a bigger concern for me than Test level and I have only been in TRT since 2012 . Oh , I am 58 and about to have shoulder surgery and Hip replacement 90 to 120 days later - so I can be back in the gym and backpacking by ..... hopefully May 2019 and get back to backpacking the AT before I hit 60 .
