"Level up" has been a term that is very familiar to many of us. We hear
it mainly in video games, but also while in the elevator or on the
escalator of multi-floored buildings. We also tell ourselves to "level
up" indirectly by trying to be better than our siblings or friends, or
even showing ourselves to be better than what are parents perceive us to
be when we're at a young age. Of course, we see this in various sports
as well, especially in Summer and Winter Olympic events. However, some
interpret the term "leveling" up differently than others. As per
upgrading one's car, they may change the tires for better handling.
Others may upgrade their processor to make their computer work faster. @ APH Networks
