I have no idea whether his stuff will work but I'm glad people are trying wacky stuff to find out.
There is a very weird lack of interest in slowing down or reversing aging in the scientific/medical community in general. To me it seems like it should be a top priority. Life is extremely short and extending our lives shouldn't be a terribly hard feat given there are plenty of biologically immortal and long lived organisms all over our planet.
* unbounded population increase * wealth and power directly proportional to age * dictators and other bad people not dying
Not insurmountable but all of those big problems would require massive sociological shifts.
