I found these prints of Lou Gehrig's hands for sale online, so I figured I'd try to read them. The images are small so the lines will be hard to read but I can do the shape no problem. Lou Gehrig threw left handed but wrote right handed. I did a little reading up on this just to determine which hand I should consider to be his dominant hand and I'm going to say his left hand was dominant because he was just trained in school to use his right hand to write because it was the "right" way.
The fingers on his left hand are all basically straight so all of the properties each finger represents were not hindered. On his right hand, his index (Jupiter) finger leans in towards his Saturn finger which meant he overcame a fear of power or leadership. All of his fingers are pretty evenly set on his hand indicating a lucky disposition.
His heart and head lines are spaced rather far apart indicating an open mind. The heart line on his left hand is longer and more prominent than on his right, he must have become more passionate as he grew older. Each line is curved, which means he took a physical approach to love.
On both hands, his head line begins intertwined with his life line, meaning he was very close to his family and they really molded the way he thought. Both lines are curved, so he was more of an imaginative thinker rather than a scientific thinker.
His dominant hand has parallel fate lines. This means he had a great partner to support him. On both hands the fate line begins closer to his Luna mount instead of the traditional start near the Venus mount, indicating a career in the public eye. His life line also starts near by indicating a need to travel and experience many things in life.
The Mercury Line is present strongly on his right hand and vaguely on his left hand indicating some health problems.
A strong Apollo line is present on his right hand meaning he would be successful early in life.
I know very little about Lou Gehrig, historically, I should read up on him and see if any of this is accurate. All I really know is that he played baseball and died of a disease that was named after him.
