I am a 73 year old female in basically good health who still works as a business broker.  I am a glass is half full person so do  not really feel like I'm 73  more like 50 or 55.  I do have a question for you.  Is there such a thing as a weak and a strong half of your body????  It seems that everything measurable happens to the left side of my body.  My mother always said her right side was her weak side but if this is possible mine is the left.  Starting at the neck, I have a arthritis on the left side, I had shoulder surgery on left side, low back pain on left side, knee surgery on left side, and a sprained ankle a year and a half ago that still gives me trouble.  It swells periodically, stings, & itches and now spider veins are spreading.  Is this all just coincidence or is there really such a thing as a weak side and a strong side?

Thanks for any insight you can give me.
