I think possibly half the problem is that the presenters have to wear a ton of make up for their shows. All this make up has to be scrubbed off and quite possibly over the years the skin isn't as happy about it as much as the normal person in the street with a bit of foundation, blusher and possibly mascara and lippy.
Personally I don't have a problem with seeing people age, I have more of a problem not seeing them age with smooth foreheads and chunky inflated lips.
Lots of people suffer with health problems, you are blessed not to have
, but we know that chemo, steroids and the stress caused by being ill can age you very fast. We know, because we read it in the presenters blogs, that many have suffered and still do with health issues, therefore I think we should be kinder (not you but others who have posted).
