A new Dentyne commercial claims we spend 20,000 minutes kissing. What kind of estimator would I be if I didn't check their math?

**How many minutes does the average person spend kissing?**Couples often kiss each other several times per day

^{1}. If we assume the average day consists of 30 seconds of kissing and the average persons spends 60 years in a relationship, then we can estimate the number of minutes spent kissing in a lifetime:time kissing = (time kissing per day) · (days per year) · (years in relationships)

= (30 s per day) · (365 days per year) · (60 years in relationships)

= 11,000 minutes.

That’s an average of 11,000 minutes spent kissing in a lifetime. The commercial’s claim is well within what one might reasonably expect. Good job, Dentyne and “stub”.

If you assume that someone has a girlfriend/wife for about 35 years of their life, and that about 1/3 of that time is spent with that partner, then all that is left is to estimate the proportion of time kissing. This proportion of time probably decreases over time, but 0.5% may be a fair estimate.

((35*365*24*60)/3)*0.005=30,660

My estimate ended up slightly over, but I may have been slightly generous as I did no research.
