Sleep deprivation causes all sorts of challenges and problems. When one doesn’t get enough sleep one’s mind doesn’t work clearly. Studies have shown that after staying awake for 24 hours one’s ability to do simple math is greatly impaired. Driving tired has been shown to be as bad as driving drunk. Moods change, depression, anxiety, and mania can be induced by lack of sleep. As much as people try to do without enough sleep it is a wonder more crazy things don’t happen in this world.

What if dogs were racist? Would they care about fur color….. “son, only play with other tan dogs”? Or maybe it would depend on breed, “honey, only play with other German Shepards, never poodles”. Better yet it could depend on occupation. “I’m a sled dog while you’re only a running companion, leave me alone”. Maybe the neighborhood they live in could be the way they choose which dogs to associate with and which to shun? Size could be the determining factor, “see how tall that dog is, they are probably dumb”. Luckily dogs don’t discriminate. Just watch at a dog park. Big black and white dogs wag their tails and play with tiny tan dogs. A service dog chases after the same ball as the off-duty police dog. So if dogs don’t discriminate then why do we?
