Fixed point observation

Resently,I've been thinking.
There're two kinds of people in the world.
One kind of people are suited for fixed point observation,
And the other are not,
The former kind of people will never change their position once they decided the place to stay.
Some prominent persons belonged to this kind.
Immanuel Kant(1724-1804), a famous philosopher, he was born in a small town
in Germany. He taught in university of this town and did a private teacher in his house and wrote many books in small town.
He never accepted invitations from universities in all over Germany.
He never set out on even a short domestic trip.
As you know, his walk has became legend.
When he started to go for a walk with clockwork precision, the villagers used to adjust their watch.
The walk was enough for him. (To be continued)
