I'm planning to open a business and i wanted somebody's opinion on my company's name. I was thinking "Be like a Rock". This name is inspired by my sick son "Rokas". My Company is all about health. What do you think? Please write back soon.

I can sort of see where you're coming from with the word rock -  I suppose it could imply strength, security & a grounded attitude etc, however I don't think that the link is strong enough.  Be like a Rock doesn't say anything about health (to me at least).

You could say 'Good Health Really Rocks!' or 'Rocking Good Health!'.

I think you need to keep thinking.  I wish you success!
