I've been playing for two years (started at 53).
I practice at least 30-60 mins every day, and I can honestly say, with that amount of time invested, I'm surprised at how awful I still am.
My fingers wont stretch, my memory is shockingly bad and co-ordination between my hands is best described as 'bloody useless'.
When ever anyone asks me how it's going, my answer is "well.......I'm not as bad as when I first started'.
I love trying, but it isn't easy - I think I read somewhere that more than 90% of people who try to learn give up within 3 months.
My way of saying, it can to be a mission no matter what condition you're in when you start - don't expect too much, but enjoy the journey
