Critique for an English Personal/Narrative Composition.

Hi, I just need someone to look over and critique my personal/narrative essay that I'm thinking of. I'm partly ESL to forgive me for any spelling errors. I think overall I did a good job, except for the introduction and the first paragraph. This is for English 11 by the way.
The statement goes; You are the first speaker, who is giving a brief introduction about why the topic of healthy living is important to you.

What exactly does "healthy living" mean? Why is it important to us? Well, eating foods that are good for us and being physically active can go a long way in helping us prevent many diseases. Things like exercising should become a regular part of our day as well. However, it seems to me that people just don't care about their well-being. It's supposedly common knowledge about having to be physically active in order to live a good, healthy life, yet you rarely ever see it being used or discussed.

Eating good food and being pshyically active can go a long way for us. It'll help prevent and defeat many disaeses, allowing us to live a longer life as well as letting us stay in a good, healthy shape.


What else should I add or takeaway from the introduction and first paragraph? I don't feel like the introduction is on topic on how healthy living is important to me, but I'd like to hear your guys opinions before I re-do the whole thing. Also, would the length of the secound paragraph be fine? The rest of the essay I wrote is fairly long, it's just the secound one that's short. Thanks.
