Framing an "average age of 40" as "an older demographic" seems a bit misleading, as the average age of human beings in America is 38. We're not talking a few sickly senior citizens here (which, even if we were, I wouldn't feel justified in writing off, but it's not). |

Your thymus is very likely to be useless after 40 due to something called thymus involution.
