Recently introduced from overseas, Japanese parks now start broadcast mosquito high-pitched noise that can only heard by people below 25 years old and annoying enough to make them runaway and not disturb the neighborhood at night.

Now based on this nifty little find, the Japanese company Epoch pushed the concept further by offering a tiny module using the same tech and that will let you check that approximate age of your date… Just selected between 3 different levels, corresponding to 20s, 30s and over 40s and you will now be capable to get a better guess of how old your date is… Nice isn’t it ?
