Just past one. The Lavaux road, between the vines and the lake. A tractor, and a car catching up with it.

00:00:12,538 --> 00:00:17,922
After lunch it's the mind that slows down. We usually blame the food.

00:00:19,609 --> 00:00:26,503
A review of studies shows the dip can come even without lunch, and even without knowing the time.

4
00:00:28,612 --> 00:00:36,135
It doesn't come from the food. It comes from the internal clock, which dips on its own in mid-day.

5
00:00:37,405 --> 00:00:44,392
A heavy lunch deepens it, but the drop was coming anyway. It was already written into the day.

6
00:00:45,115 --> 00:00:52,664
The afternoon dip isn't down to lunch. If you're driving between one and three, plan a break.
