Did this not scare anyone else? I mean sleeping too long can mean you don't live as long? What?! I need to start tracking how much I sleep, but then again my sleep comes in bursts usually so it varies and therefore I won't be able to tell how long I have to live. As of right now it is anywhere between 30 years to 90 years depending on what this study says.
If I sleep longer than 8 hours it is usually because I have been going for 20+ hours strong doing nothing. However, now that I have read this I will be so stressed about the amount of sleep I'm getting that I probably won't sleep at all.

Jesus man. That's not something lose sleep over.
Doesn't scare me at all. I've lived off 3-4 hours a sleep at night for years. These days I get about 6-7 hours of sleep though. But on a whole, I don't like sleeping. I say it takes away all the things I could be doing if I wasn't sleeping.
At the end of the day, we'll catch up with all the sleep we lost anyway. Even if it is 6 feet under.

There are a lot of things that people say will make a big difference to your life that get dismissed but really do make a big difference.
Stopping smoking, having meals at regular times (especially not skipping breakfast) and enough sleep.
Because you get used to how you feel and that is then your bar for what is normal, you don't appreciate that you could feel better. Only by doing these things do you really begin to reap the benefits.
With regard to sleep in particular, I saw a BBC documentary a few years ago where scientists were putting forward the theory that you accumulate a sleep debt as you go along, and even if you decide to start sleeping more hours in order to get back to normal, that sleep dept has to be paid before any benefits will kick in. You're effectively running in a more zombie like state to what you could be doing when your body isn't recovered and running at full power!
That probably sounds worse than the reality - normally if you've been burning the candle at both ends and feel extra tired, it can only take a matter of days before you feel normal again, but I bet that a month or so of planned sleep where you make sure you go to bed with enough time to get 7 or 8 hours would make you feel significantly better towards the end.
Of the three things mentioned at the top, I've done the smoking and meals thing - so maybe I'll experiment with the sleep thing too to see what difference it really makes to me. The first two made a huge difference in how I feel - both surprised me in how I felt as a result.

The thing is, we know that the sleep cycle is connected to production of cortisol, which like adrenaline is produced in times of stress. In the case of sleep, cortisol levels works in part to mediate sleeping (when it's low) and waking up (which is high).
Prolonged sleeplessness influences the increase in cortisol production. In the long term, it contributes to depression, high blood pressure, hyperglycemia, weakened immune system. Stuff that really doesn't work to us living longer.

I think the amount of sleep a person physically needs is very much connected with your age. Babies need huge amounts of sleep and this is not only culturally determined. The elderly (I am not courageous enough to define it!) need more sleep too. The side effects of certain medications or some illnesses (chronic disease) might effect feelings of fatigue, also. Nevertheless, assuming health is OK and no medication is involved, your're not super stressed out and did not drink coffee late at night, I figure the amount of sleep is partly genetically determined. What say you with medical backgrounds?

Everyone needs sleep. It's required simply because of the metabolic/biochemical changes that only take effect when we sleep.
To put it simply, sleep replenishes depleted neurochemicals in our brain, maintains the production of hormones like the human growth hormone which in turn, along with the lowered metabolic rate of the body helps heal wounds or increase the growth rate (like in babies and children).
It's all biologically set. It's only culture and external medication that affects this for better or for worse. We force ourselves to change our sleeping habits and ignore what our bodies tell us to do.
When was the last time you felt tired, weary, unable to concentrate or sluggish? Those are effects of sleep deprivation. We've unconsciously cheated through the way our body handles sleep and because of that we don't notice these small changes that ultimately affect us on a larger whole.
