<p>NEW YORK (<a href="http://www.thestreet.com" target="blank">TheStreet</a>) -- When it comes to favorite cultural trends, we can be downright possessive -- even addictive -- in our behavior, whether it's a new convertible, season tickets to the Red Sox or high-end Jimmy Choo pumps .
But all of those pale in comparison to what really matters to Americans -- their smartphones.
Bank of America says consumers have such a death grip on their beloved phones that they "couldn't last a day with their mobile phones."
Some demographics value their phones so much that they rank it as a higher priority than their personal hygiene (that means you, millennials.)
Check out these statistics from the study: When asked how long they could last without your cellphone, 13% said it would be less than an hour.
The largest group (34%) wouldn't be able to go a day, while 28% said they could go about a week. And 16% said they could go indefinitely without their phone.
While a week without a cellphone seems reasonable to prove you're not addicted, seeing 47% of Americans who can't last a day is, well, alarming.
We would also trade just about any favorite treat (or addiction, in some cases) to get a lost phone back, with 45% of respondents saying they would give up alcohol to retrieve a lost phone, while 34% would give up chocolate.
