If you had a Venn diagram with circles for (1) Frugal; (2) Good for your health, physically or mentally; (3) Low-lift or convenient; (4) environmentally responsible and (5) actually enjoyable, what activities or lifestyle decisions would you put at the center?

Two that come off the top of my head are

• Instead of catching up with a friend over dinner, take a walk. Much cheaper, no loud music and kitchen noise to shout over, no one trying to rush you out after you finish your meal. Not only do you move your body, but restaurants in the US are notorious for huge portions and loads of salt. You don’t have to worry about dietary restrictions or setting up a reservation.

• Drinking (safe) tap water instead of soda. You don’t have to worry about running out and going to the store, limiting sugar-sweetened drinks are one of few “rules” most nutritionists will set, and chugging a cold glass of water is so much more satisfying than the discomfort of drinking highly carbonated drinks quickly.
