The method generally employed and the expectation of results is flawed.

We need to realize that prayer isn't a tool for getting stuff...whether we're asking for money, health, or the partner of our dreams; or asking on behalf of someone else.

Prayer isn't something we give to our various gods and goddesses because it pleases them. It's a coping mechanism for all aspects of existence...pleasant, unpleasant, and indifferent. It does not directly change the course of one's life. But because it can be used to liberate our minds from the desire to control our fortune, I suspect it can have a positive effect (or at least a non-negative one) on our physical health.

The compassion generated by keeping unfortunate friends and strangers in our thoughts can be a great source of comfort to all; and can be a wellspring of relief efforts for those who have lost jobs, homes and loved ones. Relating to someone else's suffering through prayer also can help us understand and deal with our own pain more efficiently.

Just my 2 cents. Flame away if it makes you feel better...
