Apparently we differ from most other animals in the fact that we have opposable thumbs. So we can grab stuff and get dressed and eat with cutlery and do lots of other things. However, nobody ever speaks about the index finger and how important that finger actually is.
Until you can't use it. Because it hurts to bend the tip. And it's a bit swollen. And it interferes with your grabbing stuff and getting dressed and eating with cutlery and doing lots of other things.
To all those index fingers out there who don't get the attention they deserve:
You are great.
You are a great help.
You make my hand look good.
You are needed.
