And no, they aren't all academics. I think we have a healthy age mix, with some pretty good gray-haired input as well. I'm going to argue for an age column on the blue sheets so we get better data :-) Grüße, Carsten PS.: Please, don't take any of this seriously. Except for the CoRE age statistics. Dave Cridland's observations also definitely don't apply to CoRE, except that we do have the stunning range of experience that makes the IETF so valuable. PPS.: Is the overall median really 42?
