This is my motivation:
I don't want them to have to struggle like I did to learn about proper nutrition and exercise. I also want to ensure they have good body images, and making sure I
have one is the best way to do that.
My other motivation is very long-term. Women in my family tend to be rather long-lived. I'm talking 80s and 90s here. And this is regardless of our health, by & large. I'd much rather be 85 and in good health than 85 and bedridden. And now, at 26, is the time to think about that.
