how many people in the OT in the bible are reported to have lived well into their hundreds, and people use that to discredit the bible?
now they're saying that living to those older ages is quite possible by limiting your diet.
I don't doubt that it's possible to live to very old ages, but I don't think the answer is dietary. That's an awfully low tech, simple solution. One that someone would have mastered and continued to use until today.
