The human mind is a strange thing and I don't know about you guys but I used to have a weird thing happen when I was slinging a lot every day. So there was a period of time where I slung probably at least 100 stones 6 days out of the week for maybe 2 years or so and after awhile I got to the point where whenever I looked at a distant object my mind would automatically gauge the exact path a stone would follow as it flew through the air towards it. As well as the cross winds and where I would have to aim above and to the side. On a side note I used to have a similar thing happen when I would draw a lot. Every person's face I would look at for a brief moment I would see their face in all shades of gray in my head as if I was drawing it.  Have you guys ever had similar weird side effects from doing one activity too much?

Well I think a common one that a lot of people have is watching the scrolling credits of a film. After a while your brain will keep the TV screen scrolling even after the credits of stopped or you've switched to a different channel.

I definitely get ya morphy.
It's how we know we are wonderfully obsessed  8-)

yes, but don't think there is anything weird about it  :-?

Not strange at all? The slinging thing maybe, but the drawing thing is odd to me.

what's weird about it ?

To me I guess I find it strange and fascinating how the mind works. Even though it seems pretty ordinary based on some of the responses. I guess everyone experiences the sling thing.  The drawing one I do find strange. It's a very weird feeling. But either no one else feels that way or not enough people experience what I'm talking about to find common ground. 

You train your mind to do something and it does it.  Either figuring out trajectory or how to use shading to make a one dimensional object appear to be three dimensional.

Most people have to really concentrate to do what you seem to be doing automatically.

Initially when posting this I was thinking about a documentary that I had seen awhile back. It's called "The boy with the incredible brain." It's an amazing insight into what the human brain is capable of. This man is a savant but unlike most savants he's not disabled and is able to explain what is going on in his brain while he's doing the things he does. Has anyone else here seen this? It's pretty interesting.

It is completely normal.

I have a friend who owns a Black Bear compound bow and when he go to the supermarket he see the people as targets and he made the noise of the string releasing and the flight and impact of the arrows.

As the bow and arrows is a bit expensive I do the same but with the sling tassel cracking and stones flying and hitting.

I do metal detecting, and when I see jewellery on people I always hear the tone my machine makes in my head. Like Masi's class ring, bing bing bing, lol. 

Okapimike, that is very similar to what I was talking about with my drawing. That's very cool. Do you ever test it out to see if the tone you hear is correct for the type of metal you see? Or does it not get that precise?

Morphy, it's that precise that I hear the different sounds made by different shapes too. A double whisper for a thin gold chain, etc.
I also can't help mentally judging the weight, but it freaks people out when you guess their weights and want to confirm with the pocket scale.
Older ladies are usually keen to chat about their jewellery if it's good quality though. Nice old chunky buttery looking gold rings on thin bony fingers, phwoaarrr. :-*

Lol. That's so odd. I love it!  ;D

Yes I did experience that too this summer but I never was very good in my estimations I need more practice
