Solutions for all problems:

• When Palestinians bomb Israel cities. Israel army bomb palestinians with concentrate flower fragrant (or if Israel army was smart - shut down their communications - cellphones etc.)
  
• If you don't know something go to Wikipedia they got almost all definitions and probably better then any other encyclopedia.
• Feel down? Do something good to someone else beside you - in result - you will feel better.
• Feel bad? Hug the ones you love and tell them that you love them - they will love you right back.
  
• People don't respect you? its because you don't respect yourself, start respect yourself in your mind and heart.
• Having a headache? could be two reasons - one - you worry to much, second - you didn't drink enough liquids.
• Your body punishing you? maybe its because you did something bad to it? in any case you need to make it recover. So drink water, don't eat junk food, don't eat fried food, eat backed food (no cakes!), exercise, work less and have a good rest.
