*
70 units is equivalent to an increase of 10 MET-hrs per day for each day of the week (for example, running at 10 minutes per mile pace for one extra hour per day or doing child care for 3.5 extra hours per day each day of the week)
**
35 units is equivalent to an increase of 5 MET-hours per day for each day of the week (for example, playing doubles tennis for one extra hour per day)
***
7 units is equivalent to an increase of 1 strenuous hour per day for each day of the week (for example, running at 10 minutes per mile pace for one extra hour per day)
