First thing, he is funny.
OK.
Serious part of the subject.
I really didn't understand him.
He says that the backpack is not enough to carry all his stuff.
So, he adds a duffel bag to carry extra stuff.
This much is logical
But he also he says that he has knee issues and cannot carry heavy loads. This is the part I failed to understand. If he isn't carrying the duffle bag , then what is his plan ??? And if he is carrying the duffle bag, then what is his point ??
I am missing something here.
