with vs. With in "Association With Metabolic Risk Factors"

I wouldn't have capitalised with, but I wouldn't lose any sleep over it either.

Do you mean to say "I wouldn't have capitalised with, but who cares when such minor question comes to affect my dreams"?

the phrasemay have been used as a segment title, and thats why it was capitalized. I too, wouldnt lose any sleep over it, (That's a phrase that means its a relatively unimportant usage selection). Id worry about more important things in your ESL adventures.
