I'm not convinced that raising the pension age will do any good.
I worked until almost 67 yrs old (instead of 65˝ ) and was forced to retire through poor health (knee joint and lower back arthritis).
If 70 was the retiring age I'd have spent time on long term sick . . and with all the benefits that come with it, (none of which apply now I'm a pensioner). Heck if I could be bothered to push I may even have got disability payments and free parking
Just false economy, like a lot of stuff banded about as a 'fix' for a Government with empty coffers.
