For every situation like yours there's probably 10 where a product that doesn't work is advertised and people waste their money and continue suffering. This is not a problem that should be fixed by intrusive data gathering and advertising, but with a working healthcare system.
Something is really wrong with you if you think of a targeted ad instead of a doctor when you have a medical problem.
I did talk to a doctor. He quoted me $12,000 for a surgery that sounded excessive and had a long recovery time. I try to get second opinions, but doctors are so busy that I never get a call back or schedule many months out.
Oddly the wealthier I get the more I distrust doctors. Why perform a $300 tooth filling, example, when you can creatively justify a $5000 root canal and crown. They know I have the money and their kids private school ain't cheap.
if only there were some way to move beyond ads, to something where items that would genuinely benefit or brighten one's life are surfaced
