Why don't you take a bath?

I had a hard day, lots of data, many papers, many ideas crossing my mind, all ended in confusion, nothing was clear.

I went home and my wife said why do not you take a bath?

Under the shower, soaping me, suddenly, everything was fixed in my head.

But this always happens to me, the best ideas come while I am taking a shower.

It looks like someone did the experiment and found the same:

Why greater ideas come when you are not trying?

(Went to bath) … (I come back from the bath)

The problem is that sometimes an hour passes and I am still under the shower, and I realize that because my fingers get wrinkled.
