This isn't really evidence at all, but it's well known that as people age, it becomes more difficult to new memories, than it is to keep old ones[1], which is why you regularly get old people mixing up their current loved ones with old, dead people; and why "you can't teach an old dog new tricks".

If the passage of time in the human experiences is largely a function of the memories we make. It's not at all surprising that things seem to go faster as we age.

[1] There's common-sense explaination for this, but I don't think the exact mechanism is understood. It is widely observed though.
