i look younger than my age i am told much.
i have speculated about these possible reasons:
i think that my metabolism is rather slow, and that may be suggestive of slower aging as i am not "revving" as high as most people.
i do not eat very much but i maintain my body weight easily.
my hair grows very slowly. i have my hair cut every 6 months. i get it trimmed to collar length at the back, and my fringe is trimmed to 1" above my eyebrows.
6 months later, my hair has grown about 2" all around.
i shave once per week and just before i shave, all i feel is a bit prickly on my chin (i hate that feeling). i do not need to shave my cheeks or "mustache" area (that may be more a hormonal thing mixed with a metabolic thing)
my fingernails grow very slowly. i banged my finger in in a slamming door about 1 year ago, and i got a blue bruise under my fingernail that turned almost black (yeah yuk i know but whatever). over a few weeks, the bruise contracted to a 2 mm dark purple spot near my cuticle.
over the months, it rode along with my fingernail growth toward the end of my fingertip. it took a whole year for it to disappear.
-------------
also i rarely "pull faces" because i am not that "moved" by anything.
i never go out into the bright sunlight except for brief periods. i almost never get in a postition where i have to squint. squinting is a major contributor to many peoples facial lines i think.
i only got sunburned once in my life. i dislike direct sun contact.
---------
when i lie my face on my pillow at night, i always snuggle into it until i feel no stretching or pressure on my cheek. my girlfriend lies on her pillow and just goes to sleep and when i study her face, i see that she has folds in her face that are created by the position of her head on her pillow.
she does not feel this folding of her facial skin (i have asked her) and is not aware of it. these folds will lead to fault lines that will be the blue print for the wrinkles that will be a feature of her elderly face.
-------
on another level of thought, wrinkles must be genetic to an extent. all young children have preformed wrinkles on the palms of their hands. also there are little wrinkles on their feet. if i just concentrate on the palm wrinkles, i realize that the wrinkles are areas of thinness in their skin which facilitates ease of grasping.
without them, it would require more muscle power to grasp an object.
and moreover, without them, the dermal layers would be damaged with repeated compression. wrinkles are like hinges that larger skin masses use to easily change position.
so i think a persons face and body are predetermined to develop wrinkles or "hinges" that make movement easier. i guess it may be easier to pull a facial expression with a wrinkly face than it is to pull one with a smooth face due to the fact that it is crisscrossed with hinges.
i actually have no idea about it apart from idle speculation so that is all i have to say.
