Notes
ACE touchscreen question "In a typical DAY in winter, how many hours do you spend outdoors?"
The following checks were performed:
- If answer < 0 then rejected
- If answer > 24 then rejected
- If answer > 10 then participant asked to confirm
If the participant activated the Help button they were shown the message:
If the time you spend outdoors in winter varies a lot, give the average time per day. For example if you spend 1 hour a day on each weekday and 4 hours a day on the weekend, the total hours in a week is 13 (5 + 8), so you spend approximately 2 hours a day.

Coding 100329 defines 3 special values:
- -10 represents "Less than an hour a day"
