You'll known when it happens, with me it was in 2021 when I fell up the steps into my local butcher and lost whatever dignity I had left. There comes a time when you start having "falls" and now there's a birthday card to celebrate that fact.

A birthday card with a picture of an elderly gentleman lying at the foot of a set of stairs. White and light blue text in an angled dark blue box above him reads Happy birthday! You've now reached that age where you "have a fall".
