It is not hard to find a doctor who will be fairly lax in his medical examination, if you really want it. The 60+ pilots I have met, have in vast majority shown a rapid decline in skills once they passed 60. I have seen several who really should have retired, but kept going to pay for the many ex wives or desired to retain the perceived status. Pushing retirement age further than it already is, is an accident waiting to happen.
And no, I am not advocating for my own sake as I upgraded years ago.
