what causes tiredness?

[OneEyebrow]

what happens inside your body? is there a way to keep energy levels up and is there a way to reduce how much sleep your body needs(no side effects allowed)?

I was going to post a similar question, as I've been feeling very tired these last few weeks! I expect it's a nice time of year to go for walks in the evenings & nose at all the lovely Christmas trees & dec's in peoples windows! So thanx Tartanwizard, I shall get out my scarf, gloves & boots & trot on!

Very encouraging - thanx TW.
