All you have to do is type the sentence above you backwards.

This is hard.

.drah si sihT
It sure is!

!si erus ti!
No long sentences.

Why do you want me to write long sentences, fine, it is going to be harder for you!

!uoy rof redarh eb ot gniog si ti, enif , secnetnes gnol etirw ot em tnaw uoy od yhW

Did you have to write such a long sentence?

?ecnetnes gnol a hcus etirw ot evah uoy diD
Yes, I did, or else it would not have been a challenge for the next person.

This is the longest sentence ever........yeah it is, its the longest ever, it will keep going and going and going and going and going and going....it will never ever never ever stop, its torture that won't stop and it will keep going on forever and ever and ever and it will be endless and painful to type backwards and it still didn't end and it is getting longer and longer and longer and longer....and it ended, not, it will keep going and going on it will get bigger!

If you want something harder then try typing this sentence backwards perhaps I'll try making it as long as I could even as hard as I could, but then again it will be an impossible sentence that will be quite challenging and hard for you all, it will contain words like Acetylseryltyrosylserylisoserine and floccinaucinihilipilification maybe I'll put another word in like methionylglutaminylarginyltyrosylglutamylserylleucyl
