Tea No Sugar

I read that tea could help brain to memorize better.
When I went to Jkt for first time, I got confused, why ppl here drink tea without sugar?
Taste so plain!
Taste just not sweet as me, lol.
Now, it's usual things to me.
Tea No Sugar accompany me every morning.
Life can not be sweet forever, sometimes you feel bitter like black coffee or plain like tea no sugar as I drink this morning.
