You know how your fingers get all pruney and wrinkly when you’ve been in water for a while?
According to Mark Changizi, an evolutionary neurobiologist, “the wrinkles act like rain treads on tyres. They create channels that allow water to drain away as we press our fingertips on to wet surfaces. This allows the fingers to make greater contact with a wet surface, giving them a better grip.”
You may think that this all happens because your fingers are absorbing water - think again. When nerves to fingers are severed, this unique acclimation does not occur. It’s thus most likely controlled by the nervous system.
our neurons. amazing.

I decided to get this as my first tattoo because when I was diagnosed with diabetes 10 years ago I knew I would have it for life. It plays the biggest role in my life everyday. Good or bad. It also doubles as a safety measure incase EMTs need to help me in an emergency, they will know that I have Type 1 Diabetes. In all I love this tattoo and how it came out. The best thing is that the person who does my tattoo’s is also one of my best friends so I enjoy getting them. Done by Kevin Lockwood out of High Voltage Tattoo’s in Batavia, NY. That entire shop is awesome.
