BB has spent most of his long life on the road, for many years playing 300+ gigs, most of 'em one-nighters. He is well up in age, and famously diabetic ~ here in the states, he is prominently featured in TV commercials for a blood-sugar testing device.

So, whether or not he has announced that he won't be coming back to your area (as he apparently has in regard to the UK), any opportunity to attend one of his concerts could, quite conceivaby, be your last chance.

As long as he keeps at it, despite his health problems, etc., he still can play and sing as well as ever, so ~ enjoy!
