I never really thought about pensions when I was young, but even if I had, the rules seems to change so often - especially for women. I find it hard to advise my own children, other than to try to make sure they are saving something - I know those in "traditional" employment now must be offered a pension, but if you have a series of limited contract, globally based jobs then who knows and there will be many with career gaps.
Pensions are now part of a divorce package - even if both partners are in employment and there are no children.
thought I would get a state pension at 60, current prediction is 66 - and counting! so even the best planning was thwarted.
Women generally are have lower salaries and more career breaks so their pension pots will be lower. It is very difficult to predict the future ie what the retirement age will be, what the life expectancy will be, how living costs will change, what provision there will be for social care, and if your family will be geographically available and willing to help.
