However, when I talk about adhering to the rules (and I will apologise for not being more clear here) I am talking about the guidance... NOT the legislation. Because, it me, it is more important that I mitigate any and much risk as I can in order to not make others seriously ill (or worse). The reason being, my motivation is not making others ill/dead and/or contributing towards the overwhelming of the NHS. Perhaps your motivation is to simply avoid being fined.
But you are choosing to do something the government didn't legislate for.
Maybe you have your personal reasons and that's fine, but you must see that those are your own personal reasons and they may or may not be shared with other people.
It's like... I don't know, veganism? You can refrain from eating meat if you want to because you care about animals but unless it's actually illegal to eat meat then you can't really blame other people if they have personal reasons for doing it.
In Scotland the message is exercise once a day. I go out more than once a day for exercise because I'm not actually getting any exercise when I take my kids for their exercise. We don't have a garden and I don't believe any of us are getting enough exercise. I'm choosing to prioritise my health because I think the healthier I am, the further away from an unhealthy bmi, and the more VIT D I get, the better chances I have of fighting a virus (that's not even deadly in my age group anyway!)
The park is a 30 second walk from my house and I give everyone a wide berth.
If that isn't in the "spirit" of save lives then I don't know what is.
And remember the lockdown was actually about saving the NHS. If everyone who gets it serious has space to be treated in hospital then the more people who get mild cases the better.
Have you ever considered that perhaps they didn't legislate the "spirit" of the message for a reason?
What if we ALL except keyworkers locked ourselves in our houses for 3 months. The virus would still be in circulation. The day we came out of lockdown and moved to social distancing it would just start ramping up again, the numbers would rise just as they did in February when the message was "wash hands, social distance, self isolate with symptoms". There wouldn't be enough immunity in the community and it would spread like wildfire anyway.
I do believe the reason the gov made so many exceptions in the legislation is because the virus is supposed to spread to an extent. That's why those most at risk are shielding.
