I'm going to take a gamble that general weight gain is true.
I'll also state that by and large the population of this country learned no lesson from this pandemic.
Have people largely vowed, or more importantly will make an effort in their personal health that would enable them to handle such a respiratory virus the next time around?
Are they teaching their children a lesson learned from The Great Pandemic of 2020/21 that the overweight, and those with lifestyle related conditions such as diabetes, cardiovascular, conditions etc. did so poorly, and that these people should make an effort to secure their own health in the future?
Not likely, and certainly in very small numbers.
Here's what "we" learned: Carry on like you usually do, don't change anything about yourself, and when the next pandemic comes along - a vaccine will be available in less than one year.
