Recommend telling your kids that back in the day the length of time it took to dial a phone number was proportionate to the sum of its digits
@internetsdairy kind of crazy that the UK emergency number was 999 in the age of dial and cradle phones. It was fun tapping on the cradle to dial as a party trick tho
@graham_knapp I think it might be that it was 999 on purpose so it was harder to dial accidentally

@internetsdairy @graham_knapp

It was hard to dial accidentally and the 9 was as far as you could turn the dial, so you didn't need to do anything other than just spin the dial as far as it would go.

@david_chisnall @internetsdairy @graham_knapp No. Zero was beyond nine to generate ten clicks (in the UK at least). https://en.wikipedia.org/wiki/Rotary_dial#Function (further down the page the reason for 999 is explained too).

Somehow, I completely forgot that phone numbers contain zeroes. In spite of area codes all starting with one. I blame Sunday.
