There is a list of astounding new inventions. There are trucks with cameras in front, sending footage to the back so that cars behind can actually see what is ahead. It has prevented dangerous passing scenarios on winding roads.

There are remotes for locking your door, with the added perk of informing a homeowner of who and when anyone entered. 

There are cool sieves that filter out the trash from the ocean. There are a lot of seagulls and dolphins that would contribute to that Kickstarter. You know. If they had money. 

But there is one that especially caught my attention. Someone invented a chip to place on your back. When you slouch, it vibrates, reminding you to stand up straight. You are free to buy it or not, at liberty to wear it or not. You can even choose to ignore the signal. But then again, you can decide to respond. 

I don't know how my friend who is working on eclipsing the snarky comments from her daily conversations is faring. Maybe a snark sensor would come in handy.
