I completely agree with Bluebell. If everyone in the world stayed at home except for essential travel for one year then we may stand a chance of getting the virus under control.
I can see that this would affect the travel sector of the economy badly but the consequence of continual lockdowns will affect lots of other sectors, hospitality, entertainment, retail, to name a few. Not to mention giving our children an uninterrupted education.
I also agree withDoodledog that we are confusing want with need when we say we must have a holiday and agree with Jane10 about the over use of 'the affect on our mental health'. we all feel low sometimes, we have all had periods of sadness and times when we feel sorry for ourselves but let's not confuse our disappointments with real mental health issues suffered by some.
Surely we are not so fragile that we can't survive the lack of a holiday for a year or two.
During World War II our parents and grandparents went without a holiday for six years or more for the good of the nation. In fact many of that generation never even went abroad for pleasure.
I know some posters will tell me that their family working in the NHS have been under such pressure that a holiday is essential but it isn't really, there are many ways to unwind in our own country.
I do appreciate that some have indeed gone the extra mile for us but I do think that avoiding non essential travel, for the greater good, would benefit all in the long run if it slows the virus spread right down.
