As the older generation live longer, many of us will reverse roles with our parents. Here are the best ways to help a long life be a good life

Parenting no longer starts and stops with our children. Nor is it confined to those who have children. In a time of unrelenting change and ever-extending life, most of us will – at some stage – find ourselves “parenting” our own parents.

Indeed, many of us – particularly those who had families later – will find ourselves simultaneously parenting our kids and our parents. In one breath we’ll be begging our children to swap French fries for vegetables, and in the next breath we’ll be urging our parents to exchange cake for sardines. Little wonder today’s midlifers are known as the sandwich generation.
