45 is certainly an issue with a lot of people. Including me.
So is the square root of 1, Pi, and the number 'E'.
Infinity has been known to cause a little confusion too. But I prefer to ignore it due to practical difficulties. I'm not a fan of it.
I don't like 7, or 386, or 41, or 5281 for various reasons, but I agree. 45 has been a national embarrassment today.
Wait, what nation are you referring to?
