Isn’t it weird that when you have a fever, your body feels cold? Your internal temperature is above normal, yet you feel colder than normal. Some say it’s because your body’s thermostat (as controlled by your hypothalamus) sets the temperature higher, so despite being at normal temperatures, your brain says you’re cold, so you start shivering and getting chills. So your brain is actually deceived (stupid hypothalamus!). That explains why the common cold is considered a virus — it’s hacking your internal network, changing values and making the system malfunction. It all makes sense now!
And on the subject of colds, here’s an idea for a funny video. Have a hidden camera capture the facial reactions of people taking the liquidious version of DayQuil. That is some nasty-tasting medicine!
