The best six doctors anywhere
And no one can deny it
Are sunshine, water, rest, and air
Exercise and diet.
These six will gladly you attend
If only you are willing
Your mind they’ll ease
Your will they’ll mend
And charge you not a shilling.

 – Wayne Fields

I love this short poem and I will use it as a guide for my next 5 months of vacation in New York. To make sure that every day contains sunshine and air through walking, rest through sleeping and taking it easy, exercise through running and yoga, and diet through eating well. So simple and so effective at the same time.
