At lunchtime on the North Harris campus of Houston's Lone Star Community College, students stream through the lobby of the student services center, plugged into their headphones or rushing to class.
Many walk right past a small information table about the Affordable Care Act.
The table is the brainchild of Megan Franks, a health and fitness professor at Lone Star. She knows that young people may be key to the success of Obamacare. The insurance plans need a mix of ages and a mix of healthy and sick people to balance out the costs for everyone and young people tend to be healthier.
But, many young people are confused about how to sign up. Others feel like they can't afford insurance, and don't realize there are subsidies available that could help them. Just getting overworked students to stop and learn about the law, Franks says, is tough.
"If you say 'Obamacare,' they know what you're saying. If you say 'Affordable Care Act,' they walk by without any 'ding, ding, ding' (of recognition)," she says. "So then we throw out the word 'penalty.' Zoom! They've never heard that before. Penalty? That really tends to be a hook more than, 'Gee, you really need health care.' "
Franks says many students at Lone Star are low-income. They often work. Some have families to support. Others struggle to find gas money to even get to class.
"I still think so many of them are [in] survival mode: 'Health insurance? Really? You know, I've got to get to work,' " she says.
She could be talking about Adan Castillo. He's 19 and hoping for a career in law enforcement, or maybe the Marines. In addition to his classes, he also works.
Castillo actually used to be insured. He paid his parents $55 a month to keep him on their health plan.
But he says it just felt like throwing money away.
"I just stopped giving it to them," he says. "There are other important things I have to do, like paying for my college books, classes ... gas. Gas is expensive nowadays."
But Adan's girlfriend, Leslie Gonzalez, says insurance is important. She's an accounting student.
"Well, he needs it," Gonzalez says. "Because what if let's say he doesn't have it right now and he gets in an accident. He's going to have to pay everything out of pocket, and what if he doesn't have it?"
Gonzalez works part time as a bank teller. She says she will sign up for insurance at work as soon as she is eligible.
The stereotype about young people is that they think they're "invincible," that they don't need insurance because they're young and nothing bad will happen to them for years.
But most young adults don't actually think that way.
Two recent surveys, one from the Kaiser Family Foundation and one from the Commonwealth Fund, reveal that cost is the real issue. (Kaiser Health News is an editorially independent program of the Kaiser Family Foundation.)
Young people think health insurance is expensive, and they assume they can't afford it. Often, they simply don't know about the subsidized plans offered under the law, or how to get them.
Taylor Castille is a nursing student in her second year at Lone Star. She has logged on to HealthCare.gov, but says her first visit didn't go very well.
"I finally got on the website the other day," Castille explains, "and it was kind of confusing to me because I didn't understand ... if I would have to pay, what would I pay, what I'm not paying. It was really confusing, and I got stressed out all over again just looking at that. So I just left the site and didn't even bother to go back."
Castille still wants health coverage. Last fall she suffered a series of fainting spells and seizures. After a few visits to a hospital emergency room, she now has $30,000 in medical debt. And she still doesn't have a diagnosis.
"I have all this debt and I'm 21," she says. "I haven't bought a car, I haven't done anything. I don't have the debt because I was being irresponsible. I have the debt because I was sick. And I couldn't control that, so now I'm stuck with that."
Castille later visited the campus information table and got a flier on how to sign up for a health plan.
So far, only about 25 percent of adults who have signed up are younger than 34. The federal government is hoping to nudge that proportion closer to 40 percent.
The deadline to enroll for all ages is March 31.
