Where I used to live the bus that took people to the industrial section of town only went there 3 times throughout the day.
It was particularly frustrating for me cause it was the only bus to take you remotely close to the courier’s office to pickup a package. But its schedule appeared to be timed with the changes in shifts at the factory.
Rainbow vacuum cleaners are built to last and since they don’t use a traditional grab bag you’ll never have to worry about finding replacements. But I don’t know if they got any Roomba style ones.
I suspect that the magnetic feature you desire is pretty unique to the usa. Anywhere else I’ve been in the world was chip or tap. Swiping the card would throw an error to use the chip only. So that country is just really far behind.
Someone tried to explain this to me once. They said that the original formulas for insulin are really cheap, it’s just the manufacturers have all agreed to only make the expensive formulas to maximize profits since it’s not in their best interest otherwise.
I think that line of reasoning will quickly become a ouroboros situation when you think about the details of cause, effect and desire.
I suppose the best outcome is the one where you’ve destroyed yourself and are replaced with a nearly identical person sans the reason you changed time and the butterfly effect of everything that stemmed from that.
At worst you’ve duplicated yourself and have a wonderful opportunity to observe yourself blissfully unaware of the reason you changed time.
But depending on which flavor of time travel used. I suspect the most likely outcome is you’ll continue doing this again and again. Something always misaligning with your goals potentially unaware that anything has already happened. Never seemingly perfect or that time becomes this window of experience looping, endless eight style.
