I gave a presentation last week with materials that I thought were well thought out, but during the Q&A session

"I don't understand"

I am now in a spectacularly depressed state after that.

At least, I was in a daze this past weekend, unable to muster the energy to do anything.

My weight dropped 1 kg in one day.

However, I, at my age, 'understand' this "I don't know" very well.

I have no doubt that I have also used this phrase wildly in my company (especially at invention brainstorming sessions) for the past 10 years, and I made many people (especially younger people) depressed.

In that sense, it is probably quite important for seniors like me to be depressed by such harsh words from time to time.

But it is still hard to be depressed.

Even if it works for a diet.
