- If answer > 1440 then rejected
- If answer < 10 then participant asked to confirm
- If answer > 300 then participant asked to confirm

If the time you usually spend doing vigorous physical activity on each day
of the week varies a lot, give an average of the time you spend doing vigorous
physical activity.
