Its very funny to watch them exercise and everyone does it too, nursing moms, little kids. Some swim, some power walk and some lift boulders. I got a little kid that was born with builder skill to become and apprentice builder by exercising. Works great, thanks for the tip.
The sick stew works too and no one died. Would have to do it a lot to really move the skill bar, tho.
I wish they had percentages instead of those bars, its hard to tell how much more skill is needed to become masters.
