9 Interesting Quirks About the Human Body (2 of 5)

2. Human hair is ridiculously strong

Just a single, long strand of hair has the ability to lift 100 grams (3.5oz) off the ground, while a full head of hair can withstand up to 8,400kg (18,500lb) of weight without sustaining any damage or being yanked out.

3. Your nostrils take turns breathing

You probably aren’t even aware of this, but at any given time as we breathe, one of the nostrils is doing most of the work while the other is congested. Around every 2 hours the roles become switched, with the second nostril doing most of the breathing while the other is congested. Also, right-handed folks generally use their left nostrils more often for breathing.
