The technological empire begins with polymer materials

I had an operation in the next city last year. I went for a review yesterday afternoon and came back this evening.

The re-examination results were pretty good. There were more than 20 nails in my head. The doctor recommended removing them, but I didn’t want to go to the operating table anymore. I just wanted to keep them. The side effects didn’t seem to be particularly serious.

I'm so tired that I went to bed, so I won't write today. Please forgive me.
