The notion of time All days have 24 hours, 1440 minutes and 86400 seconds. Every day has the same time, each day is exactly like some other, but sometimes, this is not our sensation One day it's Friday and suddenly it's Monday. What happened to Saturday and Sunday? What was up? The answer is that you are happy The time flies when we are spending a good time with the relatives, friends or partner. When we go to see an amazing show, film or performance or when we are reading an awesome best-selling book The time flies too when we are on holidays because we are having fun. Nevertheless, another day it's four o'clock and much later it's four fifteen. What happened? What's up with the watch?? Is it broken? No, the answer is that you are unhappy. The time drags when we are bored, worried or sick. When we are waiting for, someone or something, or when we are cleaning, ironing or doing the homework I cannot understand the reason for it mostly happens this way. It would not be better than the time drags when we are happy and that the time flies when we are sad, worried or sick?. This world is upside down
