Just came across this news item this evening about Revlimid. Apparently, when taken in very small doses, it generates immune system responses that has anti-aging responses in perfectly healthy people:

It's not clear, as best I can tell, whether these benefits would apply to people taking the drug for as a myeloma treatment.
This news has already made it into the general press overseas. See, for example, this report:

So it probably will get coverage in the press here in the States as well.
