9 Odd Things That You Need To Know About Your Body

8. Why you wake up with morning erections

Well, it may just come to you as a shock. But, men do have erections every hour to hour and a half during their sleep. This is because the combination of blood circulation and testosterone production can cause erections during sleep and are a necessary part of REM sleep. This happens continuously throughout the night. So, waking up with an erection or not, is just completely a chance thing.

9. Are you an innie or an outie belly button. Here’s what it means!

We all do have belly buttons, but whether they’re an innie or outie completely depends on the doctor who tied off or clamped the umbilical cord of yours. Most people have innies, bit there are some with outies too. Outies usually occur when more of the umbilical cord is leftwhen it’s cut, leading to more skin leftover once it dries out. So, after the leftover dried up, and fell off; all you were left with at the place is your belly button.
