I can see I'm getting older with the last comment.
Now I really like sleeping 6-7 hours a night, if I sleep more I feel worse than being overtired.
Things I've been reading lately have guided me to this being the best way for you to get on in your day. Apparently if it were possible, to have two lots of sleep, power naps are much better than one huge sleep from 10 till 7 the next morning. Its too long a time for your body to be incapacitated in bed.
Anyway I'm trying it. But then my lifestyle has changed. I started running 6 months ago. I love it, though sometimes couldn't be stuffed. First time for doing exercise in well forever. I can run about kilometre now, its still a little hard but it feels great to realise you can run and see how much further you get everytime.
I think both things are great for my body and mind.
