A dear friend gave me a suggestion yesterday.
"You need to trade your shotgun for a rifle."
He noted that were I his son, he wouldn't be quite so mild with me on this point.
People are looking on me with concern because I can't seem to get my act together. The word used yesterday, was, I believe, "vertiginous." It was not intended to be positive.
Update: The inimitable Nate4D noted:
1. shotguns kill zombies far more reliably than rifles.
2. Polymaths are like shotguns, and specialists are like rifles.
3. Therefore, to be a polymath is safest, especially in a world Where Zombies Matter.
This may seem odd, but Nate4D is privy to information I cannot yet reveal: that Zombies Do Indeed Matter.
