Japanese expression ~4~ Yoisho!!

  I will teach you the word, "Yoisho".
You say Yoisho! whey you feel so hard physically.
For example, you say...
when you are lifting heavy box.
when you have sit down for a long time and then you stand up.
(we sometimes sit down on the floor or tatami. you can say yoisho
in this situation)
when you go hiking on the mountain, and start to walk on stairs.
when you are lifting a heavy child in your arms.
...and so on.
  Old people sometimes say yoisho. So, if young people say this,
he or she would be said, "Oh you are like old people".
If you are not Japanese, I think this word is useful to show that
you know Japanese language so well. If I see foreign people say
yoisho, I would imagine he or she live in Japan for a long years and
he or she know Japanese way very well.
 But I say again. Don't use this too much. Japanese people would
worry you have a lot of physical diseases.
