Yeah, the first part is correct. I'm not springing back as well as I used to. So it's important that I avoid injury. I can still do stuff like sticks... maybe... I'd probably get bored.
Working out shortens your life by about 5 years of free time over your lifespan and doesn't significantly extend it while leading to more painful ends of life.
In my opinion, gene therapy and safe weight loss drugs should be expedited... statistically, obesity is a terminal illness, yet both excess muscle and excess fat tell us to eat more, and repetitively injuring oneself leads to weight gain behavior resulting in only 3% of the population being able to stay thin for 5 years after all that. The numbers are hopeless, but if you can provide consistency such as via drugs, then you can get to your optimal weight and enjoy working out as a nice social activity without the risk of injury and have all the fun either way. Otherwise, every visit to the gym comes with fear of injury and workouts that are too conservative to be worthwhile.
So unless the frags are just a confidence placebo, I think they would be the way to go.
