I went to the hospital today.

They were confused as to why I did that! Lol.... They said it wasn't dangerous though! Lol

Well bro, I heard it and it was scary after four seconds....

I am glad to hear that there was no permanent damage done. Good luck, if you do it again, they will likely stick you in the psychiatric ward for your own safety.

Yes sir! Thank God for health insurance. I wasn't so happy about the deductible though.

Well, I have been known to react to a dog whistle when done withing about 5 feet. It felt like someone was poking around in my head.

You couldn't pay me to do that again. You can keep your money! Lol

If that is the case, you are on the road the riches! Click here: http://www.randi.org/site/ then select What We Do on to and click on The $1M Challenge. They will negotiate a mutually accepted test protocol and give you 1 million dollars when you pass it. No tricks. You will both agree to the laboratory test standards before hand.

Just saying how they would probably take care of you.

After working in the hospital for 20 years, I would have loved to been a fly on the wall listening to what they said about you after you were discharged.

You wouldn't believe some of the strange stuff I have seen. None of it is acceptable to be mentioned here.

Were you using headphones?

My guess: the site you were on may have said they were giving you a 90 KHz tone, but, if you actually heard something, it was actually something else, much lower than 90K. No idea why they'd mislead you like that, though. 90 KHz would be tough for any normal speaker to reproduce.
