Sleeping has obviously a need for all the animals to cool the brain also. Can you tell me how many hours we need to sleep at the age of 30 years? Or the routine is same for all class of people in case of minimum scale?

It really depends on people. I know that my parents are around 55 and don't sleep more than 5-6 hours a day during the week and 7-8 during weekend and don't seem to need more.
Most of time it's between 7 to 9. What is important is to have a really repairing sleep. 4 hours of repairing sleep is better than 7:30 waking up several times and have pain issues.
