Human beings, more Emotional than Rational

Human Being is said by Scientist to be homo-sapient. In Logic we studied the difference between human beings and other animals.In our studies we were told that man is a rational being while animals use their instinct instead of their reasoning. But in Life I have discovered that more than 85% of human beings are more ruled by their emotions which is actually the cause of violents in the world. People tends to make common mistake when it comes to sudden decision taking. When we make decision, we ought to put many factors into consideration:,today,short-term and long-term. But many only think of today and forget tomorrow, maybe because the bible says that " ...tomorrow would take care of its self". In actual sense that is very right but there are still certain situation when we need to know that no condition in life is permanent. Who has no cent today might have a 1000 dollas tomorrow and who has today might not have tomorrow.Who is in Prison today might be a free man tomorrow and who is a free man today might lose his liberty tomorrow.And who is a tenant today might be a landlord tomorrow.
Finally I would expect us human being to be more rational than emotional, respect both poor and old, weak and strong,free and imprisoned.It's only in this way we can grow in our wisdom to live better life in this world.
