Select last date check all rows

Hey,

I have some slow query issues where i do something like :

SELECT x FROM y WHERE datefield < NOW() order by datefield DESC LIMIT 1

The result from EXPLAIN XXX shows that the row count is 100k+

Shouldnt it be able to just fetch the latest row if datefield is an index?

The table holds like 150k rows, and it takes about 5-6 sec to execute such as query.
