I don't know the practices of issuing medicals outside of the USA. I can assure you that using the current USA aviation medical exam as a tool for weeding out those sliding due to age is completely worthless other than catching those with chronic easily diagnosed conditions or those with one foot in the grave.
There is a reason certain US AME Physicians get a huge proportion of commercial pilots.
The current system is inadequate for judging fitness for flight with a aging pilot group. The birth certificate seems to be well used for a million other arbitrary reasons including meal discounts for seniors. A true sign of selfish self importance is to deny it's use when it doesn't seem to work for oneself.
