You probably think TB is a disease of the past. But that’s not because we’ve beat it. It’s because we’ve moved it elsewhere.

Our bodies have an innate ability to tell the time – it evolved so that we were inclined to rest when it was safe, and were keener on travelling or hunting and gathering when food was plentiful. The sun and our body’s ability to perceive its light kept our internal clocks ticking along consistently.   But today, many of us spend most of our days indoors, and much of our night...
