The approximate 15 percent of the population who are southpaws were being celebrated on August 13 with the hashtag #lefthandersday, which took off on social media as a way to honor those whose writing and eating plights often go unacknowledged. Social media, of course, noted the suffering of lefties everywhere, but didn't seem to do such a comparable job of pointing out the financial costs of "other"-handedness.

So Vocativ did some preliminary digging on the internet to compare left-handed products with right-handed counterparts and found a substantial economic difference. Let's take going back to school, for instance:

Scissors cost you $6 more.

You'll spend an extra 7 bucks on a tape measure…

And $11 more on a computer mouse.

You could pay over $7 for a pair of chopsticks instead of getting them free with takeout…

And the only can opener you can buy is more than three times as expensive as the only can opener sold for you.
