Here is a high-detail, non-professional image of Helena Lindgren. A respectable fight against aging, but there is
- medium-size wrinkling in the forehead, nasolabial folds and horizontally along the neck; and
- perpetually tense-looking neck tendons (BTW, is there a more concise name for this phenomenon?).
These flaws, although not numerous, shift my belief of her age to the late-30s–late-40s range. (In my experience, the combination of these specific flaws is rare in 20–35-year old women, save for ardent smokers and sun-worshippers.)
35? where do you get this number? Where do the people who say 40 get that number? Where do the people who say 30 get that number? Has there been a study that shows women begin looking old at 30, 35, or 40? . . .
That would be the "my belief" and "in my experience" parts. (There was a rather recent study on the onset of facial aging, but I'm relying on intuition — we have all seen thousands of faces in our lifetimes.)
I think some of them begin to show signs of aging earlier, and many of them later than this age. There is no magic age when aging suddenly appears. You've been feeding into a myth. . . .
Congratulations on reaching a whole new level of banality. Yes, all people recognize there's variation in the age of onset of age features — there is no "myth" to be fed into. This is why my estimate (late-30s–late-40s) is so wide in the first place (and also the reason for the "save for ardent smokers and sun-worshippers" disclaimer).
To be more specific, I believe most under-35 people don't have a combination of medium-size wrinkles and prominent tendons (even the queen of self-inflicted premature aging, Lindsay Lohan, is free from the latter); analogously, I believe most over-50 people have more signs of aging than medium-size wrinkles and prominent tendons.
And speaking of the woman in the picture I would say she looks somewhere in her 30s.
Arguing on the Internets at its best: demand "scientific proof" for other people's claims, but present similar claims of your own right after.
