"   Given the permanency of tattoos (painful laser removal aside), it&amp;#039;s a good idea to think before you ink. (Especially if you&amp;#039;ve just turned 18 and you want to get a dolphin jumping over a rainbow inside a heart etched on your lower back, but we digress).  However, there&amp;#039;s a new kind of tattoo that we would totally be down for (and it doesn&amp;#039;t hurt that it&amp;#039;s temporary). A Princeton engineering professor created a smart tattoo that can tell if you&amp;#039;re sick and then call for the appropriate help to get you the care you need. Bonus: it&amp;#039;s pretty luxe too\u2014the tat is made of gold and silk, as you can see in the photo of it on the left.  While we think the existing use is super cool (and can probably save a ton of lives), we can&amp;#039;t help but wonder how else this temporary tat technology could be used. Like to tell you when you&amp;#039;ve had too much to drink and call you a cab, or sense when you&amp;#039;re about to get your period and automatically send you a care package of Midol, tampons, and dark chocolate. A gal can dream, right?  Want more from Natasha? Follow her on Twitter or find her on Facebook. Photo: via Princeton "^^<http://www.w3.org/2001/XMLSchema#string>
