Take this with the same perspective as how the article treats correlation/causation, but I'll share an interesting anecdote. I have several family members in their 90's that love to put cayenne pepper in/on almost anything. One even puts it in orange juice if you can believe that. I tried it once... That fellow started smoking when he was in WWII and hasn't stopped. The less-eccentric/vegan/non-smoker members of the family seem to make it to late 70's.
