00:00:02,409 --> 00:00:10,275
Two in the afternoon. In the car park at the edge of the village, only one space is still in the shade.

2
00:00:11,411 --> 00:00:16,781
Ten minutes of sleep here is not lost time: you drive on more awake.

3
00:00:20,811 --> 00:00:28,527
Five, ten, twenty, thirty minutes of sleep: a laboratory study compared them.

4
00:00:29,267 --> 00:00:36,375
Five isn't enough. Twenty and thirty help, but later: thirty leave you groggy first.

5
00:00:37,416 --> 00:00:44,251
Ten work at once, and partly for over two hours. They fit into a quarter-hour stop.

6
00:00:46,406 --> 00:00:53,384
At the first signs of sleepiness, pull over. Ten minutes of sleep, a fifteen-minute alarm.
