Nice Idea WG!!
It would appear that there are now notifications in game regarding players health and the amount of time sat at their gaming systems. For me this is a welcome introduction, as this is something you know I have been trying to promote for some time now.
It states "Regular breaks will protect your health and ultimately also improve your performance"
Now you can take this on face value, ignore it, or think actually there may be some truth in this. Well, there is a great deal of truth in it, and you can find out the reasons why in my Fit4wot sections (link below).
Good job Wargaming for finally addressing this subject, on whatever scale (I wonder where you got the idea from?)
