Misplaced adverb, misprint and TMI

"How to perfectly fold a T-shirt every time:

The 30-year-old teachers viewers how in a two-step YouTube video"

Really awful writing. Why not "How to fold a T-shirt perfectly"? If you can do it perfectly, then you can do it every time.

Why is the age of this 'expert' relevant?

'teachers' for 'teaches'?

What a mess!

From an article about a popular singer

"The 27-year-old has been revealed to have had the biggest-selling album of 2015, despite the fact it was only released in late November."

Why not "The 27-year-old had the biggest-selling ..."?

Bending my rules

This was a story about a dancer, which had this headline:

"XXX reveals she needs a hip operation at the age of 46 after decades of dancing have taken their toll"

The story revealed that this was not actually the case:

"She said: ‘I’ve been told I’ll need to have a hip replacement at some point, but technology changes so rapidly that they might have invented something new by them.’"

and the final word here was a misprint which has, so far, gone uncorrected.
