Zurich to Paris (489km) is shorter than San Francisco to Los Angeles (559km).
Europeans think that 100km is a long way while Americans think that 100 years is a long time.
Yup. Door to door from south east England to the French Alps is nigh on identical if you take a plane and all then ceremony around that, or just jump on the Eurostar and travel mostly at 140mph or so.
How much work can you really get done going via airplane? How much time do you waste going through security and how well can you work crammed into a tiny seat?
Sometimes taking it a bit slower is also good for your health.
