Little bit of a rambling. I'm sitting here writing notes, made a mistake so I scrubbed it out and then I realised I can erase it out because it's an erasable gel pen. Then I remembered the old pen rubbers that did diddly squat but rip your paper so everyone used liquid paper instead. Got me thinking.
What has come a long way (for the better) since your childhood?
Photocopiers. Like, we have photocopiers now. They were revolutionary. Don't start me on what life was like before them.
Hot water services - no more stuffing the 10 gallon chip heater with briquette fragments and wood chips before doing the washing up or taking a bath or washing hair. And stuffing it again if you ran out of hot water.
Those pen erasers have come a long way. The guys driving around on purple plates use them to fake their rego book entries. Looks like real pen, erases fully.
I understand synthetic oil is nearly as good as whale oil for lubricating. I also understand that whale oil is still used in space craft and F1 race cars because it's still the absolute best for the purpose.
