You know you've gotten old when...

... when your first computer ran on less than one MHz.

@Karlos: Love that Broccoli cloud! How long do they take to harvest 50 Mt of that vegetable? Boy, I knew cabbage can produce gas but that's just another level!

And you know you're getting old when...

... you try to explain to a young colleague how math works on a 6502:
 "You've got one all-purpose register, two index registers, an ADD and a SUB command - all 8 bit and integer only, of course."
 "And you could actually do calculations with THAT? Where's the FPU???" :lol:

As a result, my mental arithmetic skills are absolutely dreadful.  I can do maths, even quite complex maths, but if you ask me to do anything without a calculator... forget it.  I think that's a bad thing.

Absolutely. I think the kids need to be able to do the calculations in the head first. Only then can they be allowed to use machines.

I'm glad my old math teacher forbade calculators in lower classes, I think we were allowed from 9th grade on.
You need to be able to 'feel' if the results you get are realistic - many times my head's faster than a colleague of mine with Win calc and 50% of the times he's even wrong. :lol:
