What this tells me is that it was very dangerous to be tourist ca 3550 years ago.
Question: did the BBC's Paul Rincon really mean '3550 years ago'; or did he hear, "3,550 years Before Present," and assume it was the same as 3550 years ago? It may sound trivial, but it's not when I'm programming a destination in my time machine.
