LaTex macro to make LaTex more human-friendly in Math?

How can I make a LaTex macro which replaces each

1. \and by the word "and"
2. \or by the word "or"

so that the nouns are not in italics?

From stackoverflow

• \text{and} or \text{or}

  If you insist on a macro, just use the normal LaTeX \newcommand.

  Masi : Thank you! Do you know how I can make an alias of \and so that it applies to \text{and}?

  Masi : It seems that I can make an alias by \newcommand.

  Charlie Martin : Hah, beat you to it ;-)

  Will Robertson : You need to load the amsmath package (or amstext, at a minimum) for this to work.

  Charlie Martin : No you don't. \text is plain LaTeX.

• In math mode \mbox{} gives the argument upright (roman) typesetting.

  Will Robertson : The advantage to \text is that the font size adjusts in different situations (such as subscripts/superscripts). Although that's not always important...

  dmckee : @Will: News to me. Thanks.
