Overthawk, even if that's true (?), if that's the explanation (perhaps radgirl might wish to clarify him/herself) then it's an entirely erroneous comparison. Why on Earth would we compare today's figures with those of twenty or more years ago? Sorry for letting medical reality intrude but the statistics are undeniable. Rates of Heart attack and stroke events for the age band 65-75 are much higher; almost double in fact, than for the decade up to age 65. Nor does the "If I pass my medical" line entirely hold up since only around a third of such events can be predicted.
