Right with you! As a guitar instructor, I LOVE working with folks who are "re-beginners".

Even with a 55-year haitus, after a while I bet you will notice that your fingers and hands actually remember some of this stuff from long ago! 

Take your time, follow a Fundamentals Course (either mine, or Anders') to make sure your technique is re-developing in ways you will be happy about further on down the path. 

Have fun! - Lisa
