I understand. I didn't mean to compare mental health and physical health, just to say that mental health should be considered which I didn't get from that - admittedly - one sentence in the tweet.I would assume they have taken that into account, and that the mental health impact of having Christmas cancelled is less than the impact of killing your nan.
It's just SO easy to say we're doing the wrong thing. Lockdown the country = people's mental health suffer / Relax rules at christmas = cases go up. It's lose/lose, which we all knew when the rules were announced anyway (or should have).
