I like to say that once you hit 30 you’re old, then every 10 years thereafter you get another “really” in front of it. So at 40 you’re really old, 50 it’s really really old, 60 is really really old, etc. I find it amusing when people argue, to which my retort is that when any of us were ~20 we thought 30 was old, and that hasn’t changed in the world…
