17 Sexy Science Facts To Liven Up Parties

2. Low Blood Sugar Can Create Marital Discord

A 2014 study at Ohio State University has found a link between blood glucose levels and marital satisfaction or, in laymen's terms, some boffins have found that ice cream makes you happy.

In the study, they asked 107 married couples to test their blood sugar levels morning and night, and to stick pins into voodoo dolls that represented their spouses. Over the course of 21 days, those with consistently lower blood sugar had stuck their spouses with more pins and, what's more, were "more willing to blast their spouses with unpleasant noises at a higher volume and for a longer time" (because apparently the study's participants were all also sadistic guards at detention centres).

So next time you feel like yelling at your SO, eat a cookie instead.
