We had a major retirement 2 years ago,at age 52
,and since then around 25% of the retired guys died of different health reasons.
(They all had a Class A medical before retirement,one even died at 52,rolling out after landing)
So,enjoy the new 65 limit of age,and best of luck for a retirement as long as possible.My bet,is that after some cases of incapacity or even sudden death at the controls of an airplane we'll see again an age limit change.
We all love this job,and maybe we have things to pay for,so I doubt any of us will retire before the limit age,health permitting.After maybe 40 yrs of flying,even if holding a good medical licence,one may crack at any time,I've seen this happening unfortunately to some good old friends of mine.
So fly safe,as long as you wish and have a nice,long retirement after that.
