Calment's day is celebrated 2 weeks from now on feb 21.
This is done by posting a selfie while consuming olive oil/chocolate/wine (Calment's longevity secret) Also (if one wants) one can tell people who you are and what you do to make humans live longer than Calment.

I expect longevity fans to join and show their support, this is a bit like the Ice Bucket Challenge, but for aging.
