This is an entry into the 16th Fortnightly Challenge - reverse-puzzling
I was using a colleague's computer the other day, and he had some ... unusual terms in his search history.
No, not that way. Just ... well, see for yourself:
total number of dead people
extra ear mutation
average number of cloudy days
exorcist scene rotating
child slavery laws
mt everest erosion
howitzer firing rate
pigeon water migration
average walking speed
Frankly, I have no idea what kind of questions he was trying to answer with those searches, and at this point I'm afraid to ask. In fact, I'm not even sure that what he was searching would answer his questions meaningfully. Can anyone work it out for me?
EDIT for HINT 1:
I think he's still pondering the same topic. I happened to see him start typing "did the rolling stones" into the search bar, but when he noticed me looking he switched to Google Maps where he plotted a route to his own house?
HINT 2:
At this point, I think he may just be going mad. I heard him talking to himself, saying "Seven? Eight? Forty-two?" over and over again.
