I seem to have ultrasonic hearing! This is especially interesting as I've been in quite a few loud nightclubs (came out of one with my ears literally ringing and couldn't hear properly).
I wonder how good my hearing would be if I had looked after my ears!
I'm 26 but my hearing is apparently that of a dog...
edit:: I asked my Dad if he could hear the sounds and he could too. So perhaps it's not reliable? Well, turns out he can hear bats squeaking too.
If it's true it's amazing that you can discover something like this about yourself after all this time. Amazing.
