Mind Bender #2 : Solution

Thanks for submitting your solutions for the last Mind Bender.

It’s interesting that most people tend to focus upon what is there – rather than what is NOT there – in seeking out a solution. So, it’s good to see that a number of you don’t place such limits on your own thinking.

However, what is unusual is to have an entire paragraph without ever using the letter “E” – which is the most popular letter in the alphabet.

Anyway, congratulations to those of you who picked it up quickly. And maybe I will have to ‘raise the bar’ going forward.
