IMO, it is not the actual numbers that matter here--it is the kind of
thinking which can affect your behavior. What to take along and what to
leave behind--how much water to carry--what to wear, etc. It points up the
silliness of comparing the gram weight of two cyclometers, and then throwing

And "Should I wear a 3/4 pound (340 g) helmet?" After all it's very

it.
