US median age grew by about 2 years per decade between 1990-2000 so that also supports thisisnotmyname's point.
Some of the decline may be due to lifestyle changes (e.g. lung cancer has probably peaked in the US) but there has also been dramatic progress in treatment for some cancers (Breast, testicular, Hodkin's).
Imperial College academic here. I haven't seen any fliers or posters around college today so this might have something to do with your lack of uptake. This is in contrast to the event you had earlier in the year which was prominently advertised around the place.
Also I noticed there is a careers fair happening today, predominantly big engineering firms/consultancies/banking, and I didn't see if you had any representation there (apologies if you do and I missed it).
