You don't seem to understand that it relates to quantity, not necessarily to length of exposure.
Was your wife's case serious? If she had only a mild infection (just a comparatively few particles) you would not have gotten many from her.
Her case was also mild. Okay, I see what you are saying. Length of exposure is not as important as quantity of Covid particles that enter your system. Got it. Mild exposure vs. heavy exposure.
In your opinion, if you have a mild experience it's not because you are healthy and have a strong immunity system, it is most likely due to having a mild exposure? If that was the case, then the reverse would also have to be true. Only those who had heavy exposure should be dying or being hospitalized - but that's not what the data says. All the data I have seen says Covid is much more deadly for unhealthy people or those with weak immune systems - there has been no mention of mild or heavy exposure.
If you do not eat right, don't exercise, are severely overweight with diabetes and high blood pressure, etc. popping handfuls of prescriptions to keep your body functioning the way healthy bodies do, then you catch Covid and die.... I think its misleading to call Covid the cause of that death. You were already shortening your life by treating your body so poorly, Covid simply sped up the process while you jabbed your fat fingers into another bucket of KFC, puffing on a Marlboro and sipping on Mountain Dew in your potato chip-crumb-covered recliner. Wondering what pill or shot you could take to feel better.
Whatever the case, what is most important is understanding that you do not need anyone's compliance to protect yourself 100%. If you think it is necessary, you can protect yourself completely from catching mild or heavy Covid, even if no one else gets vaccinated. It's each individuals responsibility to protect yourself, its not anyone else's responsibility to do it for you.
