I wish they would do that with hiking trail signs! Some use "as the crow flies" and others use the real walking distance. We have to guess which. The time it takes an average person would be a good thing to use.asking someone how far a destination is and have them reply with "oh about 2 hours"
My kids, who live in Yosemite, did that when I asked them how far they were from Bishop. Had to drive it myself to get the actual mileage.
I once was talking to someone in California when she started to laugh and said I must be Canadian. I asked what was her first clue, she replied I had expressed distance in travel time. We do it all the time.
Not a lot of sympathy for doctors... Especially when they start with...Or when a doctor ask the patient how long have you felt this way? And the patient replies, quite a while instead of 2 weeks or something else.
