Do you not have personal experience with people under 40 in America? I would bet $20 over 95% of them don't know how to balance a check book.

95% of them can’t turn a block of flint into a spearhead either. Without skills like these, how will the younger generation hunt mammoths?

Who still uses a checkbook?

And with your bank balance instantly available on the computer in your pocket, and transactions posted in near-real-time, why would you need to worry about balancing it?

I would bet $20 over 95% of them have never needed to balance a check book, and probably never will.

Why are you going on about "balancing a check book?"

I'm in my 40s. Never did it, never going to.
