I'm 60 and have been riding since I was a teenager. I took my first "formal" class at MCAS Iwakuni, Japan in 1965. I re-take a MSF course about every 10 years and each time I learn, or re-learn, something.
I've a great insurance company (USAA) but they have no interest in seeing any kind of refresher document.
Anyway, if its been some time since you've taken the course, do consider taking it again. You'll be surprised at what you forgot.
