Are you allergic to mornings?

Are you somebody who can't wake up in the mornings? Do you need two cups of coffee before you can start a new day? Do you feel awful when you first wake up? Scientists say it's all because of our genes. How did they find this out?

Researchers discovered that we all have a 'clock' gene, also called a Period 3 gene. This gene can be long or short. People who have the long gene are usually people who are very good in the morning, but who get tired quite early at night. People who have the short gene are usually people who are more active at night but who have problems waking up early in the morning. How does it help us to know if we have the long or short gene? Scientists say that, if possible, we should try to change our working hours to fit our 'body clock'. If you are a 'morning person' then you could start work early and finish early. But if you are bad in the morning, then it might be better to start work in the afternoon and work until late at night. So maybe, instead of nine to five it should be seven to three or twelve to eight.
