God has give the night in order we to go on sleep.
If rest wasn't needed to our body and brain we will be pc's and work 24/7.
First of all playing 7 days a week is a lot, it's also question who much time on daily basis you spent on poker.
Our brain need rest so you must do days off, or I would say that brain freeze will come soon.
Knowing the stress we live today, somebody think how to survive due loosing jobs, other have a little more luck and with some activities or someone with faith in God, passing this period. My word was that now we are bombarded with information's, bad predictions for our future, only negative things on tv (thats why I don't have tv in my house) stress level is high and even you think that doesn't affect you, you are in a little miss calculation.
So there is no need for special dates for rest.
If you plan to play some extra special tour with a lot of value, then you need to prepare yourself mentally.
Play when you feel good and don't have some other things that's depend's from you.
Don't push the limits even that is famous quote.
When your body and mind are tired, they are more susceptible on stress and diseases.
Good health to you and welcome on the forum I see you are a new bird
