great job tequila. there has been some discussion of using mosquitos here in Australia, i find this to be a horrific answer to a fairly mundane issue.
I have sensitive hearing, not quite supersensitive, but enough to cause problems.
There was a boy i knew who thought it was funny to play his so called silent ringtone in my presence, because he knew that my instant reaction is to slap myself in the head. Its not painful persay... but its itches and you cannot scratch the insides of your head. longer exposure to the sound causes headaches and nuasea. He eventually stopped annoying me like this, after i actually mentioned it to him. He can be a nice guy, he was diagnosed with ADD at the same time i was diagnosed AS, we seem like siblings even though we are unrelated.
I have overcome a very debilatating fear of peopled places and i am not alone in this. If the Mosquito were to be employed this would remove my ability to shop for myself in that locale; How is this going to increase takings? or decrease costs?
