Lockdown for most is going to have a negative impact particularly when it takes away the things you do to perhaps relax and deal with issues whilst leaving all the challenges like work, family, illness etc. still there. Golf course talk can often be pretty basic and probably about everything else but feelings but that connection with others shouldn't be undervalued.
I saw this yesterday, liked the bit about the guy asking him why he had his clubs on his back. Can just imagine getting some funny looks walking round a city centre with a bag of clubs on your back.
I would say anything that raises awareness for mental health and takes away the stigma of talking about it is a good thing.
