Good to hear you are playing the guitar again. I've been playing off and on for over 50 years, except for the last 15. That is when I discovered the ukulele.
For most people it is merely a toy, but once I realized the tuning was relationally the same as the guitar, and I could do stretches and play things I never dreamed of on the guitar, I never looked back. It is obviously not for everyone, but the sound is so mentally uplifting. That is what hooked me.
Jake Shimabukuro inspired me, although I am not remotely close to his ability. A guy named Kalei Gamiao is also great. While this may be heading OT, here is a clip of his playing on a $10K ukulele.
