I was replying to a post roughly answering "what's in it for me" by "what's in it for your children". All wanted to show that the 3 main reasons for going vegan/plant-based all have a strong "for the children" side to them.

There's a huge influx of people in the vegan/plant-based communities from very health conscious people. Many of them believe that science is showing that it allows them to live healthier/happier/longer/stronger.

Is that not a good answer to "What's in it for me?" :)

Yes and no. It's all true but too deep for most people. One punch to the nose works better than 3 body blows ;)

I tend to pick different strategies for the amount of time I have of someones attention.

But you're advocating the one blow will be from the "personal health" angle. With little time on my hands I usually also go for this angle, simply because I believe that all the people who'd want to be vegan/vegetarian "for the animals" would be so by now. The health angle still has a kind of novelty/news aspect to it (while being more personal and urgent then the environment angle).
