Hello and welcome.

There's several old timers here. Some are older timers then others, but all are part of the family. Don't feel bad for starting up thinking your age is a hindrance for starting now. You yourself hit on the key. It becomes part of you. You may set it down for a day or a week, but you always migrate back. It brings you joy to your spirit and soul to be able to play it. Even if in a simplistic nature. Who really cares? You're doing what you can, with your ability, skillset and limitations. If you have a hard time reading music, there's tablature or "Tab". You can even just play by ear.

I started myself a few short years ( I can say years now) ago. I crossed over 50 this year. I play and learn, but mostly, I just love the fact I can make music, even if simplistic. I learn and add things and just experiment with music in the realm of my understanding. I took my first fiddle lesson this past week and loved it. So, once or twice a month, I'll have a 1/2 hour session. I went without any in person guidance/training for over 2 years. I  just asked a lot of  questions and had the amazing people here give me advice. I learned most of my start by listening/watching Fiddlerman's Videos and reading the forums.

Now is the time to start. Don't wish you did in a year or two.
