1. Changing your diet is not so easy when the society around you has optimised for something else. 2. Culture - if your family has historically relied on meat for sustenance, you can't exactly go vegetarian with the flip of a switch. It requires a shit ton of planning, asking questions, identifying what you like, resetting your taste palate and expectations meanwhile still entailing a fair bit of confusion. OTOH, Grandma taught Mom who taught her children on how to cook meat. 3. Younger ages are tough since you would probably be living with family and decisions regarding what is bought and cooked are probably being made by parents who might not exactly share your inclinations to go meat-free.
