Never too late nor too old. I'll be 49 this year and have been 'learning' for 39 years or so. Here I am again now starting all over to 'unlearn'. I'm forcing myself to go through the fundamentals course again and amazed at all the bad habits I've picked up over the years. I'd suggest to you to pick one beginner song and put that in your practice routine along with the course lessons. Its always more fun to be playing a song you know and before you know it you're getting better and better almost without realizing it. Stick with it, at our older ages the muscle memory is harder to instill in the brain but it does come.
