treadmill. Okay. You know, like the exercise equipment. You often see in

sports centers. That treadmill. So let's take a look at the note here. Treadmill

is a piece of equipment with a flat moving surface usually a belt, a conveyor

belt that keeps going around. That you walk on or run on. Yeah. Sometimes you can

tilt it on an angle too, while staying in the same position. Or if you ever passed

by any sort of a health clubs or fitness centers , some sometimes you see people in

the window you know, exercise running on these things.

Okay and a mill, you know a building where grain is made into flour. So that's

why in the past you know. you did sometimes wonder what is a treadmill

called a treadmill ? What does it have to .... especially what

does it have to do with a mill. Tread well even though, tread has not always

been the most common word, but it does mean to step heavily on something. So at

least that one kind of makes sense. I probably hear the word tread used

nowadays more that people are worried that somebody's going to tread on their

rights. Like don't tread on me. So you hear it that way too. Like stomping on

you are stepping heavily on you. So let's continue. So this is what

tread actually means. To walk or stomp heavily on some on something. People

tread on grapes to make wine. So that might be one example. The way we use

tread. So at least when you hear treadmill, you might be able to... if you

already know the word tread, that kind of makes sense. But where does mill come

from ? All right. Let's continue. The origin of treadmill was originally used as a

device for discipline. You know like punishing somebody. It was originally

invented by MR. William Cubitt. Okay, for the use of prisoners, like prisoners in

jail. So it was to punish prisoners in jail and probably get some use out of

them for some work out of them at the same time, in 1818.

This was not originally invented to keep people in shape. So treadmill the

original idea was not about exercise keeping people healthy. No. It was

actually about punishing them. Prisoners were forced to climb the spokes of a

large paddle wheel and this wheel turned around. The energy of the device was used

to pump water and crush grain. So that's where the idea of mill comes from. It was

making flour. So kind of like killing two birds with one stone. They're punishing

the prisoners and they're also getting work out of them and you know, getting

crushed flour .So they're using the prisoners in this

way. Let's continue. The use of treadmill was abolished it was given up. It was

stopped for prisoners in 1898. Yeah. By that time I guess they thought you know,

that this might be a bit inhumane or it's never really good if a prison you

know prison just wants people to have workers. You know because maybe they, they

might do something to help get more workers. You know keep people in prison

or get people in prison. So you kind of don't want that . In Britain. All right.

when exercise became popular in the 1960s the treadmill was reborn. So

somebody figured it out. From the old-time. Hey we can make this into

exercise equipment. Okay anyway I hope you got it. I hope it was clear. I hope it was

informative. Thank you for your time. Bye-bye.
