Infinite Family ChiropracticLogo Design Contest

To all designers, I realize the infinity symbol will be a logical and first glance solution to this logo design, however, I am really looking for something that combines the family aspect of the business as well as the word infinite and the basis of the business which is chiropractic.

Other possible design concepts: There are 3 of the letter 'i' in the word infinite - might there be a way to play off them? Could they represent people/family? Could the infinity symbol be combined graphically with a human spine? Could the word INFINITE intertwine with the infinity symbol?

Just some thoughts as I think a successful logo for this client will be able to combine all three aspects in a clever and simple way.

Thank you in advance for your work and ideas!

I've uploaded a few sample ideas for infinity symbols and people icons - check them out. Looking for some outside the box ideas as well!
