As a teen, your feet are still growing and developing - which means that the wrong kind of shoes can teach your feet to grow wrong, leading to lifelong foot, knee and even back pain.

The worst culprits? According to the Daily Mail, any shoes without proper arch support - like slip-on canvas shoes and ballet flats - can do the most long-term damage to your feet.

On the flip side, the healthiest shoes you can wear are sneakers (as long as they're worn with socks and tied tightly) and any other mostly-flat shoes that support your arches and hold your feet in.

That doesn't mean you need to toss all your favorite shoes. Just be smart about it - don't wear your heels or ballet flats every day, especially on days that you'll be doing a lot of walking. And when you wear your sneakers, be sure to tie those laces nice and tight.

As a teen, having your own personal sanctuary - where you can get away from all the craziness and demands of the rest of the house - is an absolute must.

You've already got a room, but the trick is to make it feel like your own space. Which can be tricky if you've got a limited budget and not a lot of freedom to decorate.

A lot of teens totally abstain from sex, which is great, but the ones who don't aren't always being safe about it. According to Reuters, there are more cases of chlamydia and gonorrhea in teens than in any other age group.

Chlamydia and gonorrhea are two STDs that are icky, painful and contagious. They're also totally preventable, as long as you practice safe sex and abstain until you're emotionally and intellectually ready for it.

If you're not having sex, learn all you can about safe sex so that when you're ready to have it, you'll be smart about it.

And if you're already having sex, please promise me you'll use a condom. Every single time. Okay?

Not that you need another reminder that TV isn't the same thing as reality (not counting reality TV, of course), but there's a new post up at Lemondrop that's got some warnings about the versions of high school you see on your favorite shows:

• TV teens have infinite amounts of money without seeming to have jobs. Real teens? Not so lucky. (If you're looking for some cash of your own, check this list of job ideas for teens.)
  
  
• TV teens wear clothes that can make them look bizarre to downright whorish (think Serena van der Woodsen), and they never seem to repeat an outfit. In the real world, teens' wardrobes don't stray that far from the ordinary - not counting the clothes on these real-life teen style stars.
  
  
• TV high school cliques make no sense. Why in the world are the popular kids still hanging out with the gleeks on "Glee"? (Because it's fun to watch, that's why.) Get the real scoop on making and keeping friendships before some of that fictional nonsense starts to seep in.
