You really shouldn't test that theory, though.

Zero knowledge of proper foot care, plus long wear and tear often leave the toes of old age pensioners rather painfully entangled.

A pair of compression socks prescribed by a podiatrist might do the trick.

Bats use echolocation much like dolphins do.

Creatures with echolocation abilities served as inspiration for the development of sonar.

Down in the caves where bats like to sleep, sonar would be very useful.

Echolocation is also used by Toothless from the How to Train your Dragon series. (netflix series).

Fantastic Creatures & where to find them is another series which might use the latest sonar technology.

Great movie that is, I wonder if there is more series of books or movies/tv shows with echo-locating creatures.

How about vampire movies, do those count since they turn into bats?

It could be possible, that would add another scary factor to vampires.

Just because vampires & bats seem to go together, doesn't mean that bats, even pestiferous bats who make a nuisance of themselves, aren't carriers of real diseases like Lyssa virus, or rabies, even if they aren't vampires in disguise.

Knowing that bats can carry real diseases doesn't make me scared of vampires, though!

Locally, vampires are jokingly considered to be pathology technicians who collect blood samples for patients' medical treatments.

My cat Blacky was nicknamed "Count Blackula" as a kitten because his fangs stuck out noticeably...
