It may seem funny to you, but retirement age is steadily rising for some time and it doesn't seem like stopping anytime soon. I fully expect by the time our generation retires it would be like 75 years.
The current system is heavily flawed and people should be looking at ways to improve it. With every passing year, there are less and less young people to work and pay for the more and more elderly. And their only solution is to work longer and longer and delay retirement, until your arms fall off more or less.
The chart is going downwards now, unlike the 20th century. I had grandparents in the 90s, who retired at 53-54 and lived 30 years of retirement.
