Comments here seem on track.
I agree that words - reverse - cure equal more snake oil.
That said There are some important aspects of a complex treatment program carefully managing medical misfires/aging, diet management- energy balance management and sufficient exercise; I believe it is possible to reduce/manage the damage and optimize ones health.
Cure and reverse are not the words I would use. The hunter gatherer gene/digestion system which is ancient with few mods/gene improvement do not
facilitate the words cure/reverse.
Nor looking for the single answer - garlic rings/stake in the heart/silver bullits for vampires and a unified field theory sole answer to the mess also seems far fetched.
