We've all gotten used to seeing working dogs keeping passengers safe at our airports, but the Transportation Security Administration (TSA) is apparently giving them a makeover.

Sort of.

After discussing with experts and partners, top officials at TSA recently decided floppy-eared dogs, like labs, have a more friendly and calming effect on passengers and particularly children than pointy-eared dogs, like German Shepherds, according to TSA Assistant Administrator Michael Bilello.

"You never get a second chance to make a first impression," as the saying goes -- but a new survey says you have less than 30 seconds to make that first impression.

According to ABC News a survey of 2,000 Americans commissioned by the company Dollar Shave Club and conducted by OnePoll, you have exactly 27 seconds to wow somebody...scientific proof of why first dates and job interviews are nerve-wracking.

The researchers behind the poll discovered that 85% of people get a good impression of somebody based on their scent alone, which is why nearly 70% put a lot of thought into how they smell before meeting somebody.

Other key takeaways might seem like common sense: Acting arrogantly is a huge turn-off, as is dressing poorly, and not making eye contact. Conversely, being polite, being a good listener, and smiling score you points.

Confidence is key, with 83% saying someone who is self-assured is more attractive both as a prospective date and as a prospective employee.

We hope you're paying attention to these tips, because three in five people say they know just 15 minutes into a first date whether they'd be up for a second one, and it takes just 20 minutes to know if they'd want to take you home.

And, as if that wasn't enough pressure, the average person says they'd pull the plug on a date in just 16 minutes if it's going south.

Perhaps that's why two-thirds of those polled said they Google their prospective dates before meeting IRL.
