I used to eat sticks
Did you eat other odd things besides sticks?
I used to eat a lot of strange things as a child
You shouldn't have eaten sticks. You could have gotten sick or done damage to your body.
Well, I'm currently fine and I don't have any health issues.
I'm glad that no harm came to you from this habit of eating sticks, but I really hope that it was just something you did in childhood.  It is dangerous to eat things that your body can't digest, because they could do real internal damage.  You were fortunate not to be hurt as a kid, but don't try it again.
