Are concurrent sentencing and circadian rhythm similar in any way, and if so how?

No, they are not at all related. Circadian rhythm has to do with cyclical activities in the body. Concurrent sentencing has to do with criminal justice application of punishment.

The thing they have in common is that they are both demonstrably real.

They are both loosely related to the concept of time.

@zenvelo The OP is in what way are they similar, not how they are not at all related.
@LuckyGuy That’s one way.

@stanleybmanly That Many people believed https://en.wikipedia.org/wiki/Harold_Camping is demonstrably real. Polio is/was real, and the vaccination against it is also real. To say x and y are demonstrably real to answer the question how they (x and y) are similar is saying nothing.

To say they are similar in any way other than initialization.is demonstrably false.

@zenvelo What is the purpose of the word _ initialization_ in your post?
As well, Re. “is demostrably false”, where is the demostration?

@flo “Initialization” means “to use the initials of a term”. Both concurrent and circadian start with the letter C. That is their only similarity.

The demonstration is that when you propose a similarity, I will demonstrate that it is false. You go first.

You are fortunate that @zenvelo & @LuckyGuy are tolerant souls. Demonstrably is just a short way of saying “can be demonstrated.” The fascinating thing about dealing with your questions and answers is that I can never decide whether or not you are deliberately stringing us out. I will tell you frankly, that if this is the case, you’re the best I’ve ever seen at it. Initially, when I read this question, I took it that you were pulling my leg in a variation of “who’s on first?”, which is actually the way my conversations with you always read. I really cannot decide whether you have the genius to co-opt us into Abbots opposing your Costello. But if you ever want an example of the “demonstrably obtuse”, have a glance at this thread. Anyway, I once again sit here confused; not wanting to hurt your feelings, but on the other hand, unwilling to allow genius to float past unacknowledged.

By the way, I challenge you to apply your skills to the words “initialize” and “initially”, both from this thread.

The only way that a pencil and a pen are similar is that they exist, not that they are used to write with, ... I guess?

Why don’t you tell us how circadian rhythm is similar to concurrent. I have no trouble finding similarities in a pen and pencil.

@zenvelo
1)Look at the OP, you already answered it, there is no similarity
2) The OP asks if there is any similarity what it is it? There is no indication that according to me there is.
3)And even if you’re shown that there is a similarity, you’ve declared that you will refuse? to see it.
4) Look at your 1st answer and my response.
