I guess the most obvious and most likely thing that 2019 will bring is pretty much the same things as 2018 bestowed. Somehow that doesn't seem the right thing an observer about the ageing business should be saying - 'just read what I said about 2018'.
I have no doubt there will be the usual round of longevity conferences and innovation events that will be as memorable as they were in 2015, 2016, 2017 and 2018. Lots of ground breaking technologies and insights and lots and lots of hand wringing that 'something must be done'.
