A pension is not only for when you retire, but is also a good way of providing for your partner and/or children in the event of your death. As a member of PDN, you not only accrue a pension for yourself, but also for your partner and children. These pensions start immediately in the event of your death. This is the case even if you have by no means reached the age of retirement.
Check what has been arranged for your partner and children and what you can do more for your pension. Do you not have a partner? Read about the choices you have in that case.
