Longer life expectancy means that people have to live off pensions for longer
Low income jobs do not provide good pensions so they will struggle while in the job financially as well as when they are a pensioner - may lead to poor health - not able to afford nutritious food, exercise or other things to stay healthy
May have healthcare to pay for - pension may not cover all costs to live healthy
Living off a percentage of the money they made in their working years saved for when they retire - they may have been in poverty while earning as they may have had a low income job and they were saving for retirement but they then can struggle with poverty again as a pensioner as they may not get enough
