Now with digital photography, we've learned that we can't really trust a picture. Even I can easily manipulate a picture to remove or include objects. All is not as it appears.
We all know human hearing is limited. As we age, we lose high frequency sensitivity. Many animals respond to frequencies even youthful humans cannot hear. It is only recently that scientists found that elephants communicate through very low frequency sounds--sounds that travel tremendous distances in their native habitats. We know that sounds exist that we cannot hear.
Similarly, our senses of touch, smell, and taste are very limited. Not only do our sensitivities to these vary, but our interpretations vary too. Something that tastes salty to me may be perfect for you. Pleasant odors to you may be
