You also mention cigarettes and alcohol. Those are two fast track ways to age yourself if you do either and worse if you do both. It's not my business only that you asked for input. The research is behind me on this, as I trust you already know. We drink and smoke and worry, all three recipes for an aged face and damaged body far too young. I don't mean to preach to you as you are far too smart for that. However, I am also smart, and made horrible decisions as do we all. I would lovingly invite all of us to consider the cost of worries about what is immutable instead of investing in our long term health and happiness.
