This is it!

As time goes by and your heath deteriorates - why is it that you are fully aware that you are not doing the right things, but somehow you just eat that extra biscuit - even if reason is telling you not to?

Habit, having the food available, and the behaviour of those around us.

Hello,

I think we don't realise quite how easily habit drives our behaviour - once you've set up in your mind that the response to something is a biscuit, then it becomes like a conditioned reflex, and you have to spend some time consciously undoing that.

But it can be done. You can establish new habits if you put in the necessary mind work.
