Fruits picked fresh in the tropics are in a different league than what you can buy in stores usually, even if you spend a lot of money in expensive/gourmet stores.
I personally find it very difficult to eat a lot of fruits in cold weather, and I have heard a lot of people say the same thing.
Also in the tropics you are getting a lot of sunlight and if you are near the ocean you absorb prana directly if you swim.
I have not figured out yet how to make a living and live there. Take a 3 week trip to somewhere tropical with good fruits and you will see what I'm talking about.
