All tissue in organs are under stress and cells die of. That is normal, also for young people. The body produces new cell by making copies of dna. What is problematic however is that after some time, there is a built up of errors in the dna. If those errors do not get corrected, that is when you see a decline in organ quality, what we call aging. If interested, see my other posts for more pointers.
