The risk to catching the virus is still low...because you still have to interact with someone that has the virus. I believe 3 to 5% of the public have had or currently have the virus..but the percentage that currently have it...is probably closer to .5% (these are just my estimations base on what I have read)
A good analogy to the threats of catching the virus is two people sharing the same birthday in any particular crowd....the more people in a crowd the more likely it becomes that two people share the same birthday.
If you go into a group of 25 people, statistics expect that two people will likely share the same birthday, but it is obviously still possible that nobody shares the same birthday.
The larger the group and the more groups you attend, the more likely you will become exposed to a group that has two people that share the same birthday.
Also, Predictability comes into the equation...if you are entering a group where you know the people attending, you will probably have a better chance of realizing if two people share the same birthday....
I think taking risks is up to the individual, but if you are taking the risks, I would hope that when you are in situations where others are trying to be cautious, you respect them and take similar precautions....To me it is fine to go to the bar without a mask, but if you visit grandma, it is probably prudent to wear a mask and keep social distance from her, so she doesn't have to assume the risks that you took at the bar.
