I actually enjoy socializing and I talk to quite a few people and generally wish people well in health and life . One thing I have noticed with people that I've known for several years is that of lately those that have had a shot are acting a little different . Peculiar comments , not in your face noticeable but subtle . Like a person just walking out into an intersection without even looking to see if a vehicle is coming because the light on the other side has thier back, which I'm seeing more of but an example since what I'm noticing is a more one on one conversations . It might be how much more secluded society has become , that is very noticeable .
Blood platelets also help with oxygen to tissues , doesn't the brain need oxygen ? Get it ??
