Here in Australia the politicians are pushing to raise the pension age to 70, saying "the country cannot afford to pay the pensions". (Strange how they can afford their own big pay rises, and bloated pensions after leaving politics.) They see it better for the elderly to pay taxes rather than being paid as some compensation for all their taxpaying over many decades.
Bricklayers, plumbers, carpenters etc say their bodies start giving out physically around 60 - they cannot be expected to work like a young bloke up until 70. This creates a big problem for them, especially those who have not stored up a large sum of money to live on.
Can electronic engineers, technicians and software programmers still work effectively beyond the age of 60 to as late as 70? Or have most burned out by then?
Are they still as smart at 70 as they were at, say, 40? What concerns me is old people find it more difficult to learn new concepts than young people (eg: new languages). I am in my 50's. What scares the crap out of me is if I start slowing down mentally as the years progress.
Another concern is the very common practice of ageism, where older people are illegally discriminated against in getting a job, or even in the workplace where they are employed. I personally have not experienced this, but I know of others who have.
