Human needs are never restricted, they are infinite and keeps on changing because of various factors.
For example:- a human can be satisfied by buying a certain car, but upon looking at a different and better car, his needs change and becomes dissatisfied again.

The resources are scarce to afford all that humans need. We may sometimes demand what is more expensive than what we have to acquire it. This reduces our ability to acquire it.

Human needs keeps on repeating or they are periodic, we may need the same item we needed yesterday and tomorrow we may need it again.

Some human needs are acquired free of charge, such as water, air and gifts

Human wants change with age, time and gender. Example; during cold seasons, people buy more coffee than Ice cream vis a vis, during holidays people buy more cosmetics than books as compared to during school opening days when people flock to bookshops and stores.
