> My mum is a teaching assistant and is 71. She seems as sharp as ever and mood is the same. I think it's key that she still works

I agree.

I don't necessarily buy the "loneliness" argument for cognitive decline.

However I certainly buy the importance of keeping mentally and physically active.

Infact I would go as far as saying people who use the "loneliness" term are actually just using it as a lazy synonym for "lack of mental and physical activity". You don't necessarily need to surround yourself with people to achieve it.

Whether its still working in a job, or doing non-job activities such as gardening, travelling, photography, I think keeping your brain busy and your body moving is the key.

If you revert to the cliché retirement image of taking long naps during the day, stopping only to eat and watch daytime TV, then IMHO that's where the problems start.



I tend to disagree. Mental and Physical activities require intent and effort. At older stage, your willpower alone will not push you to make you get up and do it. But if you are socially surrounded, you will have something to get moving. Also, working out or doing other physical/mental activities themselves alone gets so boring after sometime, coz there's isn't much to looking forward to.
