selecting dates in the past of future (MySql)

[lomokev]

i have a mySql query that looks like this:

$sql = "SELECT * FROM events ORDER BY event_date DESC;";

it selects everything in a database and displays all records in it in order of there date. what would i have to add to this quray to make only select records that are in the past or future?

"...FROM events WHERE event_date<NOW() ORDER BY..."
