I have held this for many years with first purchase back in 2012 and its a bit of a never sell just sitting their growing and has averaged 21% PA for me over that time.  I bought this as I just think this is such a strong sector generally.  Everytime I use the healthcare sector I always feel there is a plot to transfer my wealth or taxpayers funds to someone or something in this sector and price is not considered in any transaction or if it is it is non negotiable.  As I look at aging parents / relatives it seems to ramp up over time ....
