I have always identified as way younger than I am and will be that way til I am gone or down and out I hope.
I identify as extremely good looking.
Have you been doing the martial arts for a long time?
What I will not regret is enjoying that cupcake in the moment, and work to turn that into motivation to be extra active and have a salad instead of some pizza.
I think the trick is, to eat treats when there is a "reason" to eat, like spending time with friends and having a cake together, like I did last weekend. The killer is sitting alone in front of a screen, eating a cake.
I don't care much about dying, I just don't want to live the rest of my age in poor condition, unable to do much except sit.
