There is plenty of evidence of the physical price to be paid for CR,
beginning with reduced size for infancy-onset CR. For those who do not
aspire to be athletes, that price can be worth paying so as to delay
physical and mental deterioration by decades, let alone death..
Evidence for any mental price is not so clear yet, with CR animals
always performing at or above normal early on, and very much above
normal late in life. It appears the brain is very well defended.
