PARK LIFE. Every new Paris mayor feels duty-bound to create more parks. Jacques Chirac took old forgotten parks, refurbished them and renamed them, like my favorite, Square Marie Trintignant. Past Mayor Delanoë created 79 acres of new green spaces. We can thank current mayor Anne Hidaldo for removing the wretched 'love locks' on Paris bridges which may be equal to creating 100 new parks for the peace of mind it gives us.
How walking in nature changes the brain'. "A walk in the park may soothe the mind and, in the process, change the workings of our brains in ways that improve our mental health...etc., etc." If you can't get out to stroll in nature in L.I., Rio, Edinburgh, London, Key West etc. try Vivian's Garden book. It should have almost the same effect.
Institute du Monde Arabe's spectacular new exhibit (both indoors and out).
JARDINS D'ORIENT de l'Alambra au Taj Mahal will be the hot ticket this summer in my opinion. If you're a mad gardener head here, not the Louvre. Even if you're not a garden nut, you'll be endlessly delighted.
