Nietzsche said that appearance lasts longer than you think.

This means that

Since appearance is important

It means you should continue managing it.

Even people in the 1800s say things like this....

Cleanse your skin

Hair neat (I got a short haircut recently)

I will try my best up to that point, but

We should only eat things that are good for the body and mind.

It is actually difficult for me to only eat good things.

I'm living on processed foods...

While eating, I was worrying, "Is it okay to do this?"

Me, gobbling up food!
