On Sunday, I went for my fourth Corona vaccination -- and for the fourth time, I experienced an adverse reaction for the first time.

It was not so much a high fever, but I was so intensely thirsty that I could not sleep.

I took cold medicine, gulped down water, and stayed -- it was pretty painful.

I was quite surprised because my previous adverse reactions had been "arm hurts" -> "done".

If this is an adverse reaction, it is frightening to think of a real corona infection or illness.

I will continue to bash out both the corona vaccine and the flu vaccine.

After all, I am so gutless that a high fever from the flu makes me want to die.

Aside from that.

My wife and I often synchronize our physical condition.

In particular, the synchronization rate of daily weight gain and loss is almost 100%.

When synchronization fails, the person on the side that lost weight is allowed to be called a 'traitor'.

Although we boast such a high synchronization rate, I was the only one who suffered from the "adverse reaction damage" this time.

But this time, I have a clear reason -- because I have been (and still am) really, truly, inexplicably overworked and exhausted in my head since the beginning of this month.

In other words, we have put the corona vaccine in a place where the patient could have collapsed from overwork.

I thought, it is natrual that adverse reactions will come

This time, I didn't call my wife a 'traitor'.
