We all know that the best way to lose weight is to starve yourself and exercise like a maniac. So why is it that Parisians can eat rounds of Camembert larger than their heads, never step foot in a gym and still manage to fit neatly into one single metro seat? Now, it is true that they cook with fresh, seasonal ingredients, don’t overdo portion size and take time to savour every bite. And you certainly won’t see them sitting on their butts circling a multi story car park for half an hour. But even so. I call bullshit. 
The real answer is…STAIRS. Beautiful, old, windy, timeless, I-can’t-possibly-have-another-floor-still-to-go stairs. In a city where real estate is nuts and an elevator comes with a big price tag, it’s not uncommon to trudge 106 stairs up to the charming shoe box you call home. And God help you if you have suitcases. That’s after attacking endless flights of stairs in the metro. And for some, there’s a stepladder still to climb to get to bed! Putain! That’s a lot of stairs, and two very skinny legs. And you know what? It’s worth every torn ligament. I’m massaging mine now with cocoa butter.
