Not the subject here but golf is a good workout for a 45+ loving sports. At least when played with intensity...
It also forces me to work my flexibility, abdominals, glutes and so many muscular groups where I need both strength and precision.
I get to play in soothing, nice and calm environnement as opposed to a dirty and noisy city.
And sometimes I meet nice people I can share a game with.
In the long run I now I can play as long as I can walk without help, so for a long time if destiny allows me.
Not many outdoor sports are that kind late in life.
