ome years ago I was involved in "Loss of Lic Insurance" costing, I dont remember the exact details but I think the highest rate of medical failure and sudden mortality was between mid thirties and fifty years of age ,at the time there were many Canadian pilots flying "Non Sked" who were sixty five plus, but sked pilots were grounded at sixty, maybe these figures are still available and might prove usefull if one wishes to fight these regulations.
The heart attack rates are highest between 50 and 60 then tail off but there is no evidence based reason to EASA regulations too much perceived threat rather than demonstrated threat protection.
They will do as they wish unless someone says no and challenges them in the EU courts and that is the problem.
As with 3rd country licences that works and its not the EU courts but a serious threat of EU courts which will often suffice and remember it is the commission not EASA who decide! EASA are rule makers not instigators
