on a few occasions i have experienced the feeling of everything around me going slow, two examples are when playing cricket and i dived to catch the ball and also when playing football and the rare occasions when I have shot and scored a goal, after asking my mates they have at somepoint experienced something similar is there something in the brain that causes this feeling.

I've noticed, like many others, that dogs hate bicycles and tend to bark or attack them and their riders.

From my observation it's not as simple as it first appears; sometimes I've noticed that dogs simply don't register a bike approaching them, and are then really surprised when nudged with the front wheel even though they've  seen it coming and presumably smelled the rider approaching too, and the rider was shouting and ringing a bell. In these cases, though, stamping a foot down works wonders.

It seems to be all about footfalls/vibration being the key factor that most dogs pay attention to. They see a person apparently gliding along without any obvious footfalls and it either freaks them out, or they completely ignore it and don't perceive it as a large object approaching.

My question is "why should this be?" What possible evolutionary reason is there for ignoring the sense of sight, smell and hearing in favour of vibrational cues? Is it that chasing prey through sunlit and dark areas renders sight less effective than vibration sense? Is it that in a wild pack of dogs, there's constant noise and confusion so footfalls are the most reliable way of sensing a threat?

What is going on here?

Sometimes it also appears to exhibit pitting (with no visible insects to be found -- though it's unclear, with all the packaging, if some of the pits were developed during manufacturing) and a slightly rancid (?) taste. White chocolate of similar age seems to be less affected. Caramel centers in chocolate seem to dry out with time, leaving a dry residue.

Chocolate can melt in one's hand, but slight cooling can also make it hard enough to damage some dental work. What accounts for such change?

People can lose their sense of sight, hearing, smell and taste.  But can anyone lose all sense of touch?  I suspect this wouldn't happen because the touch sense is distributed throughout the body's nervous system, but wonder if brain damage could cause such a loss.  It seems as though it would be extremely difficult to survive if you couldn't even feel the floor when standing or walking or your chair when sitting.

I was wondering if people that are blind their whole lives have dreams. If they do dream, can they see things or is it just sounds or feelings?

I've heard that your brain calculates the position by the time difference between the sound reaching one ear and the other. However, i'm sure this is wrong! If there's a loud bang a short distance behind you, how do you know it was behind you? The sound would reach both ears at the same time, so the source could be infront of you, or even above you!

We can all see, hear, touch, taste and smell.  Dolphins can use radar.  Pythons use infra-red.  Anything else?
