What do or will they look like?

This is probably old news to many but I got to see it first hand.  An out of state family came to visit for the week.  If you're interested, I can readily describe the tops of their heads.  That's mostly what I saw while they were here, except of course when at a restaurant.  They are apparently, well on their way to the 'Chin on Chest Syndrome'.  Whether sitting upright or reclining in the Lazy Boy, they were in the syndrome position.  Again, for you who might not know, this position is a down the road, many years, causing upper back and neck deformity.  It is preventable but, you must have the courage, strength and long term determination to perform what is necessary to save them.  You must, not once, but many times, take away those small, rectangular things, I think they're called 'tablets'.  They have other names, but no matter.  You must not only take them away but hide them, at least occasionally.   This is where cleverness comes in, especially if teenagers are in possession of these little 'boxes'.  They can out think you in a second.  There is one other solution.  This may be harder.  Explaining (excuse me while I laugh) why this 'chin on chest in not healthy) and may need to be repeated many times.  Putting pictures of 'older' arthritic people on the refrigerator may help, or not, but no harm in trying.  When all else fails, but only occasionally, relax in your favorite chair and have a glass of weak wine....................................marge
