I would also like to add that I am very suspicious of a table with 80 columns.
Offhand, it sounds like poor database design where someone was trying
to put all the eggs in one basket (figuratively).
Further, what was the exact query?
Queries of the form SELECT * will always be inherently slow with
tables that have many columns. Ideally, you only want to select just
the columns that are needed.

I reserve the right to fantasize. Whether or not you
wish to share my fantasy is entirely up to you.
