R Is A Velocity Measure, Defined As A Reasonable Speed Of Travel That Is
Consistent With Health, Mental Well-being And Not Being More Than, Say, Five
Minutes Late.
"R is a velocity measure, defined as a reasonable speed of travel that is
consistent with health, mental well-being and not being more than, say, five
minutes late. It is therefore clearly an almost infinitely variable figure
according to circumstances, since the first two factors vary not only with
speed taken as an absolute, but also with awareness of the third factor.
Unless handled with tranquillity this equation can result in considerable
stress, ulcers and even death."
-- Douglas Adams, "The Hitchhiker's Guide to the Galaxy"
