Five, right? Sight, smell, touch, hearing and taste. According to the author of a book I was looking at recently we have at least eight. Those previously listed and these: The ability to sense heat or temperature, the ability to sense pain and awareness of the location of our body parts. The first one makes sense because I don't have to pick up a burning log to know it's hot or touch an icecube to know it's cold. I kind of agree with the second one also as I've eaten some bad oriental food before and had some severe stomach pain. I've been trying to get a handle on the last one though and I can only come up with two fer instances. If I have a ball in my left hand and after turning my head to the left throw the ball in the air, I can catch it in my right hand without looking at the ball. The other fer instance is someone that loses a limb and feels phantom itches or pains from the missing appendage. Do you think there are other senses that humans have and if so what are they?
Now that I think about it, what about senses that we lack that you feel humans should have? The ability for plumbers and construction workers to sense that half their backside is hanging out when bending over would be a good start IMO.
The ability to sense when not to start a nonsense thread would be nice, too.
