>The "now" is superfluous, completely fucking up the intent of the sentence. If it's so good to quit smoking, it should be good anytime. Why now? What about other times? Not so good? That's the other half of what's wrong with the sentence. And the obvious "when is that 'now'?" question - at the time when the sentence was composed, written down, printed, read for the first time, seen on a thrown away empty pack months later? It even isn't clear whether it's "quitting now" or "now reduces".

Verbal games are fun, but usually fruitless and often annoying.
Saying "Now is a good time to do x" doesn't even remotely imply that other times are not as good.

On the other hand, the intelligent use of the language seems to be under more attack of late than I can recall.

Here's a snippet of a job solicitation I got today (some changes to mask the identities of nincompoops)

"Note: If interested please send your updated resume to idiot@idiots.com and include your salary requirement along with your contact details with a suitable time when we can reach you. If you know of anyone in your sphere of contacts, who would be a perfect match for this job then, we would appreciate if you can forward this posting to them with a copy to us."

Good thing he mentioned "updated" isn't it?

I was going to suggest an unsuitable time, but thank goodness, he straightened me out.
I do that all the time- tell people to call me at midnight, when I'm sleeping.

Hmm " a perfect match"? How about a stupendous match that approaches perfection?

It would be a really neat trick if I could find one outside my "sphere of contacts" (I hereby nominate that phrase for verbosity honors - 2017)

By the way, fella, anyone is not "them."
