Run kart and feel the mystery of change! !

I have the same situation. At first, I played the marathon PRO, and I felt terrible when I went there. Later, I bought PXT, and it felt super cool, but I felt sticky after running for a long time, so I kept taking it out. I feel good when I buy cotton. After all, people generally think it feels good. But now I feel that cotton is not easy to open and slippery! But when I open PXT again, I feel clean and not slippery at all. Maybe a car has been driving for too long and my brain is a little tired. Reminds me of the adaptability of smell. Hehe, almost.
