Sibling rivalries are a fact of life… Or are they? It turns out, psychologists have identified some simple parenting techniques that are proven to help siblings argue less, and get along much better. Here’s what to keep in mind, according to psychologist Dr. Laurie Kramer, founder of the Family Resiliency Center in Chicago:

First, always praise good behavior. Dr. Kramer says one of the dangers of only speaking up when kids misbehave is it often sends the message that’s the ONLY way to get your attention. But kids need to know you also notice when they play nicely, and help each other out.

Also, when it comes to discipline, avoid comparison statements that seem to pit one child against another. For example: “You’re older, you should know better”… or “She’s smaller, and not as strong as you. Let her have that toy.” Dr. Kramer says comparison statements often make kids feel like rivals, instead of teammates. And if you make exceptions to rules just because someone’s younger, smaller, or weaker, that’ll create resentment that builds over time!

Dr. Kramer says we should also model good behavior for our kids, on how to play fair. Say, by letting the kids see you and your partner take turns sharing the remote, to decide what to watch on TV… or letting them hear you discuss how you’ll share responsibilities, like chores.

Couples fight more about money than anything else. So it’s no wonder some couples hide their money issues. For example:  

• 15% of married people have a bank account that they keep hidden from their partner. And 1-in-10 people say they’ve lied to their partner about how much they earn. And another 10% lie about how much they spend. Experts say a lot of couples hide money because they want to spend without being accountable to their spouse. And people lie about what they spend to avoid arguments. But it’s going to come out at some point, and 30% of people surveyed said they felt that hiding purchases or bank accounts was financial infidelity, and they considered that as harmful as having an affair. 

• Here’s another money truth, which shows just how powerful a motivator it is: A lot of people admit, they would marry someone for their money. To be exact, more than half of all men and women say they’d marry someone they were only “slightly attracted to,” as long as the person had money. Psychologist Dr. Elizabeth Lombardo says this makes sense because a lot of people think having more money means they’ll have more security. But over time, Dr. Lombardo says money will not make up for deep flaws in a relationship and a lack of love.

• Another money issue couples have: Their happiness is influenced by how much money they make. A Cornell University study found that, in general, husbands who earn more money than their wives are more satisfied in their relationship than men who earn the same, or less, than their partners. But when women are the primary breadwinner, they tend to be less satisfied with their relationship. Researchers say this comes from our deep-rooted idea of “traditional” gender roles. 

But know this: You’ve gotta get to the heart of your money issues and talk about them. Because a study at Utah State University found that couples who disagree about financial matters once a week are 30% more likely to divorce.

What’s the most important thing you can do during your next check-up? Ask your doctor questions. That’s because doctors usually only spend 10 minutes with each patient, and mostly on the physical exam. So, here are 4 potentially lifesaving questions to ask at your next check-up:

• First: What’s my BMI? BMI stands for “body mass index” and it’s a measure that tells you how appropriate your weight is for your height. Your BMI also reveals whether or not you’re at increased risk for everything from diabetes to heart disease.

• Another question to ask: Should I get the shingles vaccine? A lot of people assume that shots are only for kids. But there are dozens of vaccines that adults should get, like for shingles, Hepatitis B, and tetanus. And if you don’t ask, your doctor could forget to review what you’ve had and what you need.

• The next question to ask your doctor: Is there anything in my family history I should be concerned about? Knowing which health issues you’re at a high risk of developing, like cancer or heart disease, makes it much easier to spot symptoms and prevent those problems. Plus, getting treated earlier could be a lifesaver.

• And the final question to ask your doctor: What’s one lifestyle habit should I change? This is an opportunity for your doctor to tell you exactly what your big issue is, and for you to focus on improving that one bad habit. Like you need to sleep more, stop eating junk food, or control your stress levels.

In job listings, there are plenty of confusing buzzwords and phrases. So we’re going to decode those key words, so you know what a company is looking for – and if you fit the bill! These translations come from job search strategist Melanie Denny:

First: What does it mean if a company says it’s a “fast-paced environment?” Denny says that’s frequently code for a heavy workload with deadlines to meet. And it typically means keeping up is crucial for keeping the job.

Next: A lot of job listings say they want someone who’s a “self-starter.” Denny says that usually means you’ll get limited training, and need to come in ready to hit the ground running – and come up with solutions on your own.

Finally, what should you make of a job-description that says it’s looking for a “ninja,” “rockstar,” “jedi,” or “unicorn?” Denny says vague superstar titles may indicate that the company doesn’t actually know what they want. But they generally mean the company expects you to know – and do – a lot of different things that don’t neatly fit into one category. So you’ll need to be flexible.
