I think defined benefit schemes will be all changed to defined contributions schemes, for this reason - people live too long. Minimum retirement age will also keep getting adjusted. Most private sector pensions in the UK are already DC schemes. The invested savings future retirees accrue in DB plans run out before the beneficiaries are 99, and those schemes will collapse unless bailed out. Healthcare costs will also be a huge problem with extended life spans, unless technology miraculously guarantees healthy life until death.
