This is a more somber episode. Not the usual, lighthearted faire I've posted previously. Today I'm by myself talking about helmets in an effort to plead with you to check yours. How old is it? Should it be replaced? What's out there now that might be better than what you have?
The second part get's a little touchy-feely, so I'll let you know about 10 mins from the end when the helmet part is over.
Stay safe out there, and look into a helmet with sphirical MIPS!
