The retirement age has been repeatedly described as “arbitrary”. It’s certainly not. When the increase to 65 was authorised it was after extensive research. Scrapping the age limit altogether was considered and expressly rejected. Risk factors for heart and stroke rise very steeply after 65 no matter how many times you repeat the word “arbitrary”
This is absolutely correct.
The FAA despite intense pressure being bought to bear by the airlines, has resisted because the science does not support the alleged discrimination.
Th pressure is not a result of science supporting a contention, rather it is commercial in origin as retirement rates increase due the impact of demographic trends. All regulators ought ensure before extending the retirement age any further that medical science supports the commercial genesis of an increasing crescendo of drum beats.
