Some where in this forum I seen something about why they do laundry. I first noticed them doing laundry after med level 2 was bought. I realize I may be all wrong but in real life clean clothes reduces disease and pests like ticks and fleas and this could be the basis of why there's laundry.

The designers have put in some pretty cool side hassles that make the game more than just build up the society.

Just as the school when used regularly, once or twice a year, appears to make smarter kids. FYI they won't learn about breeding and they do learn about whatever is checked for interest. Unchecked don't seem to learn from school.

I can't prove any of this as only a few kids have came out with adept level skills but isn't that reality?

i use to the school to get the kids of their hairs

My villagers start to do laundry when I clear the blockage of the lagoon... I think the kids' skills come from their parents.
