Small children are well known to be afraid of voids (closets, under the bed) in their sleeping area. Knowing this, why don't we design children's rooms to eliminate them?
I'm not a parent, but going by pop culture, it seems like literally every child has the same fears.
In pre-modern times, I imagine that they'd be sleeping in the same room as the parents, but if modern notions of privacy don't permit that, seems we could at least design an enclosed capsule or something.
Speak for yourself. My home is entirely sharp angles and unsecured towers of broken glass and rubbing alcohol suspended in petroleum jelly that also slicks the floor. I will brook no weakness in my home.
Comfort ya. But we do not succumb to irrational fears either. Our more to the point, it may not be healthy to say place ten locks on our doors because we think someone is trying to break in always.
