Being understimulated is as bad as being overstimulated. Uninteresting small talk with shallow people; repetitive tasks that require no imagination day in and day out; endless, unchallenging drudgery of any kind – all as likely to make me implode as stress and overstimulation.
I would rather wander around the store for 30 minutes in search of a particular item than be a normal person and just ask a salesperson where I can find it.
