Yes it is worth learning - I am well over 60 years old and started with Mavis Beacon 8 from a magazine cover disc some 3 years ago. It was the best thing I ever did and has enabled me to type quickly and mostly accurately as long as not too many numbers or symbols are involved. I found that the Microsoft Natural shaped keyboard suits my fingers as it gives a bit more space for my old hands. If you practice an hour a day you will be amazed that after 3 weeks or so you will have mastered all the alphabet keys. I say give it a go and you will soon forget about looking at the keyboard while you type.
