One day numbers appear above each person head

What kind of stat would be most useful?

Number of thoughts they have thought

1.Number of lifetime sexual partners: slut/cheater detector
2.Number of people murdered: killer detector
3.Number of friends:popularity meter
4.Number of years left to live.
5.Health out of 100%
6.Karma score or morality meter.
7.Place in "people sorted by wealth(including assets)".
8. True chronological age: people wouldn't be able to lie about age.
9.Number of lies told(lifetime): updated per each new lie.
10. Place in "people sorted by their contribution to progress of humanity"

Some useless stats that can be handy in rare situations:
1.Number of total words spoken.
2.Number of relatives.
3.Last phone number used by person
4. percent of time per day spent sleeping
5. Number of pets owned, excluding insects.
6. Length of distance traveled today(counted from midnight)
7.Time since person last talked to someone
8.Number of times a person masturbated in the current year.
9. Time since person last bathed/showered
10. Total weight of all food/drink consumed today.

Time in dd:hh:mm:ss since person last engaged in any sexual activity:masturbation included.
