Yes, mine too - but the increments are getting bigger with each passing year. That probably means my proportion of mutant mitochondrial DNA is growing as time passes.
At 72, I think I'll double up on my multi-vitamin.
At 64, I’ll raise you a mutant and stand with the DNA I have.
The multi-vitamin may be OK...depending on the type of activity you have in mind.
If your hand has more than a full house, take two aspirin and call me in the morning.
