When do you help?

Tamar and I know someone who suffers from high anxiety. Whether it is an anxiety disorder or not, I don't know, but we (and she) all know that there's something going on there....

Over the weekend, I saw an ad in a magazine looking for participants in a study of anxiety who would get a bunch of free benefits (treatment, etc.) if they signed up.

It was clear that the person we know would benefit from at least calling.

The question: is it our place to suggest or even call attention to the ad?
