Regardless paralysis rot does not discriminate based on age, injured at 20 I Imagine my bones will be as brittle As they will get - due to paralysis related osteoporosis - in 10 years after injury or less, whether I live to 80 as a quadriplegic or not! Same applies with drop foot, bladder shrinkage and hardening ( these two with absolute certainty) etc. etc. I’m not a paraplegic so I’m not going to destroy my shoulders over the years which would be very much age conducive, Although somehow I did develop tendonosis In my shoulders. Again infection ( i’ve got UTIs with basic E. coli that is resistant to every antibiotic but two IV antibiotics) , bladder stones, kidney stones, autonomic dysreflexia ( however the damage from my frequent AD may show it’s self later in years, and as anyone I will be more susceptible to a stroke with age) dealt with it all since day one, bedsores, septicaemia, pneumonia I may be more susceptible to it with age in combination with paralysis rot but I’ve had all of it from the age of 20 and continue to have Whatever one of them every now and then… A good diet has helped and always will help. I’m rambling, I digress, basically I’m not worried about my age, my youth is void ( you yourself know this, i’m sure you have had many experiences that a teenager, 20-year-old etc. should not normally deal with) there are 50-year-old C8 quadriplegics that don’t have high pressure bladders, a syrinx, have very little susceptibility to AD etc That are in far better condition than me, and have not experienced much of what I just stated above. Paralysis from a spinal cord injury is a very serious thing, very nuanced , Very complicated. Spinal atrophy goes it goes, axons atrophy and they are gone etc. youth makes no difference it’s been five years they are gone no different than they would have been if I was injured at 40.
