Yes! The smell factor usually indicates ripeness. It's sad that the produce nowadays are grown with pesticides, herbicides, petro chemicals, fruits no longer have a fragrant smell and quite honestly, don't have any taste whatsoever. When I do buy fruit, I like to go to farmer's market and use my senses: sight, smell, sound, touch and taste, to determine ripeness.
