We have about £40k. DH is very fond of saving and we are both fairly frugal. He is 30 and I am 32.
We probably don't save enough into our pension pots though - but we do have a rental property that will be paid off by the time we retire (hopefully long before that but you never know!) so there will be a bit of income there.
These are scary times. Jobs aren't for life any more, don't come with decent pensions most of the time and finances generally feel very precarious. We certainly don't feel that we can rest easy, you never know what the future holds.
