As we grow old we accumulate experiences and memories,
we connect with people and we loose people.
When you are trying to focus on a task
especialy when the task involves thinking and planning,
even a small distraction can send you on a trail
to deep dive in your memories.
Sometimes it's the different areas of your life
that needs your attention.
It becomes critical to learn how to manage your baggage.
Younger people have this advantage and that is why they are fast and spontaneous.
