On a personal level I've been adhering to the lockdown rules very diligently and continue to do so. I've found it relatively easy because I actually really enjoy a significant amount of solitude. This particular Jackal isn't a pack animal, but I'm probably atypical!
Human beings generally are social creatures and there was always going to come a point when adherence to the lockdown started to waver. I don't think for one moment that most of those waverers have suddenly thought "Sod our doctors and nurses, I don't care about them anymore". They've simply reached a point where the mental/physical toll of isolation is making them consciously or subconsciously lose their discipline, if only to a degree. A Government therefore has to deal with the reality of human nature, or suppress it by becoming ever more draconian, which isn't a favoured option in western democratic cultures.
