I quit smoke, also, quit eating outside. The improvements were impressive: 1. Better sleep. 2. Better weight control. 3. Skin stopped being dry. 4. Better sex life too. 5. Good energy. I never measure my work productivity.
I'm really curious about eating outside. I feel that only could have improved dry skin but that could have also been improved by eating more carrots and other dietary changes. I love eating outside!
If I can install Rails 4 then I can prepare the best Curry Chicken out there. I eat more for less money and cooking became part of my hobby that helps to distress a lot.
Also, I was noticing my daily diet was based on the same quantity of dishes, what I meant was: trying different dishes wasn't normal, I hanged out always to the same places with the same menus, at the end eating a different thing was rare.
I go dinner around 2 times a month just to eat those things that are really hard to prepare: sushi, etc.
