I was just looking ahead in my Mind-Bending Puzzles Calendar for June 25/26th and there was a puzzle to go from Brain to Nexus... The requirement was that you connect the words so that the last two letters of one word are the first two letters of the next, and all words must be 5 letters long.
The solution given was:
BRAIN -> INURE -> REGAL -> ALONE -> NEXUS.
My question to you is, am I the only one to notice that you can do it with a single word?
BRAIN -> INANE -> NEXUS.
Edit: Actually I'm not because I asked my son and he came up with the same answer.
