Or people who don’t understand how a thermostat works and crank it up thinking that’ll mean it gets to the actual desired temperature faster and then overshoot to then turn it way down and repeat…
Apparently so, although it seems to have a separate history and meaning from other historical uses. From Wikipedia:
Since ancient times in Japan, the heart symbol has been called Inome (猪目), meaning the eye of a wild boar, and it has the meaning of warding off evil spirits. The decorations are used to decorate Shinto shrines, Buddhist temples, castles, and weapons.
Often with women, if they’re attractive they aren’t taken as seriously (not considered as competent or intelligent for e.g.). I don’t think the same problem exists with men so this makes sense.
The next question is what percentage of men are considered attractive? My hunch is it’s not very high.
