I've always wondered whether not starting to drink alcohol until my mid 20s have contributed to my youthful appearance and vigor. My late teens early twenties were spent playing HL1 online, SWG then dominating vanilla wow. Then I discovered a social life in my mid 20s but by my 30s I was not going out as much and hitting the gym hard. I've been tracking calories for 10+ years.
I use face serum, anti wrinkle moisturiser with SPF and eye cream. I have a full head of hair with a few whites. Not so much recently but it was not uncommon for me to get asked for ID to buy energy drinks or alcohol. Very few people I meet guess that I am in my early 40s.
I make a conscious effort to control my facial expressions eg smiling, laughter, frowning, raising eyebrows to avoid contributing to wrinkles. Last night watching a Gentleman in Moscow, I was struck by the vertical ditch inbetween Ewan Mcgregors eyebrows. Of course, his face is the tool of his trade and he needs to be able to show emotion - but I do not. I would rather maintain a wrinkle free complexion.
I sleep on silk pillow cases, however, I wish I could train myself to sleep on my back to avoid pressure wrinkles from sleeping on my side.
