so im bored at work today, reading xkcd, and i come across a semi-recent comic: http://imgs.xkcd.com/comics/fermirotica.png Using his formula, and the values for my area: Regional Density: Northern VA: 3072 per mi^2 (4.8 per acre) Average frequency of sex (taken off of numerous pages) 104/year (twice a week for average couples in their 20s) Average Duration of sex: i couldnt find a reliable number, so im using his "30 minutes" Plug this into the google Calculator (You must include units for it to work correctly), and I came up with someone is having sex within 300 meters of this office... theoretically. (multiple bathrooms, other offices, people staying late, it could work... even a pilot doing it to one of the FAs outside on the planes...) What's it like for your area?
