My 15 best tips for a healthy lifestyle:

• Refuse stress! Miss the bus rather than run!
• Learn a relaxation technique and use it once a week at least.
• Go for a walk every day.
• Drink lots of water all the time.
• Eat and drink healthily every day. Take special treats only on weekends. If you easily gain weight: eat SMALL portions.
• Choose an exercise technique that suits you, and practice it once a week at least.
• Go to a professional masseur once a month at the very very least. Or exchange services with your partner or friend, read a book about massage and practice it.
• Stop smoking.
• Sleep enough and well. (The most common reason to sleeping problems is lack of exercise.)
• Get to know yourself, and realize you are worth a good life.
• Look around you - what can be changed in your life and your environment to make you feel better?
• Keep developing - learn new things, try different paths in life.
• Be good to yourself. Let ambition rest sometimes.
• Think positive thoughts about other people and wish them well!
• Do things that you love. Enjoy life!

Health definition by WHO (World Health Organization):
The following principles are basic to the happiness, harmonious relations and security of all peoples:

"Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.

The enjoyment of the highest attainable standard of health is one of the fundamental rights of every human being without distinction of race, religion, political belief, economic or social condition."
