As everyone knows, chocolate becomes healthy once you are 1000m above sea level.
It is also one of the most effective negotiating chips/bribery mechanisms that a parent possesses (along with the cancellation of the Disney channel subscription).
Having several hundred grams of chocolate about your person means that you can rapidly rectify any of your kid’s inevitable blood-sugar related meltdowns, but also means you can force the wee nipper to straightline the mogul field so you can capture it on video and upload it to YouTube.
(N.B. Haribo is a reasonable alternative during chocolate-melting spring sessions)
