I don't usually post answers on these things, but I'm getting tired of hearing my girlfriends tell me that their hair grows faster when they get goosebumps, so I figure I'll just clear this up once and for all. No, goosebumps do not make hair grow faster. It is a myth that has been fabricated and spread around by women (and some men) who feel that their skin is prickly when they get goosebumps even if it was perfectly smooth just...

There is nothing you cannot help doing when you yawn. You do not even need to open your mouth - it is certainly possible to yawn with a closed mouth. ...

We can’t say for sure, but there are several possible explanations. One potential explanation comes from research out of the University of Nottingham, which suggests that contagious yawns are prompted by automatic, primitive reflexes in the part of the brain responsible for motor function. Other researchers think it has something to do with empathy or social cues. "Researchers have seen that yawning may not be as contagious to people with autism or schizophrenia," Meredith Williamson, clinical...

They will over feed but wont eat everything that you put in there. Just put in enough food so that all of it is eaten in 5-10 minutes or so. Any more and the excess food or fish poop will foul up the water quickly. Yes, they do. They tend to swim away from the food and ignore it or they might just keep eating.

Answer (maybe) This is a nervous reflex of our brain, just like when someone tells you that he/she is hungry, even if you're not, you'll suddenly feel hungry as well. we tend to yawn when we see someone else yawn because we somehow connect to that person's mind when he/she's not having right amount of oxygen in his/her body Edit: Another possible scientific reason as to why we do this: 1. Person observes yawn 2. Sensory input of the brain deactivates left periamygdalar region 3. Subject...

It isn't because you are tired, it is because your blood lacks oxygen. When you've been idle too long and suddenly move, you can find yourself yawning later on. That's why a person yawns after waking up in the morning. Yawning adds oxygen to the blood. If it bothers you, try deep breathing. ...

Yawning It is actually still an unknown mystery of life. Though there are good hypotheses supporting why humans and animals yawn, they are not conclusive. Any explanation about why we yawn will have to explain a number of interesting observations: Yawning occurs even when oxygen and carbon dioxide levels are normal. Yawning may make others yawn (that is, it seems "contagious") and may indicate behavior based on social cues. Other hypotheses: One is that when we are bored or tired, we just don't breathe as deeply...

No, but they will not pull so hard on the leash afterwards. It is believed that over a period of several years, a lot of the visible damage is repaired - so much of the tar, etc, in the lungs is eventually removed - but it depends on how long you have been smoking for, and how much other damage was done. ...

Well, for one thing we don't even know WHY we yawn. A quite plausible theory is that we yawn to get more oxygen because our tired bodies can't gain enough through normal breathing. Another one is that it's a way to relieve tension and stress. Yawning is almost always a sign of sleepiness and is common in the morning or late at night. When you work out remember to have plenty of rest, food and water beforehand. ...
