Just idly thinking about this because on my social media feed there are:
Nutritionists who advise on weight loss and diabetes control but are obese themselves
Therapists who are constantly saying how depressed they are
Financial advisors who are saying how bad they are with money
Does this make them more relatable to ordinary Joes or Janes? Personally, I think I wouldn't. Though on the other hand, I know a lot of doctors who smoke.
