Good medical advice from the Jewish sages of old:
1. F***ing once a week is good for your health, but it's harmful if done every day.
2. F***ing relaxes your mind and body.
3. F***ing refreshes you.
4. After F***ing, don't eat too much; go for more liquids.
5. Try f***ing in bed because it can save you valuable energy.
6. F***ing can even reduce your cholesterol levels.
So remember, FASTING is good for your health and may God cleanse your dirty mind!
