Young female rats afraid of new environments developed cancer tumors sooner than their more adventuresome sisters, a new study finds.

The researchers called the difference "striking."

The apprehensive rodents died sooner than others in the study because they got cancer earlier in life, on average. Importantly, however, the study found no difference in the length of time between onset of cancer and death in the two sets of rats.

Implications for humans?

For better or worse. For richer or poorer. At the office or at home? Those may not be the vows you remember taking, but perhaps the thought of starting a family business has come up in your dinnertime conversation. More and more couples are starting companies and working together in an effort to gain financial freedom, and spend more time with their families. The question is, can you and your spouse survive working together?

As with any major decision, creating a list of pros and cons is usually the best way to start. There are certainly benefits to being co-owners of a company. However, there are definite drawbacks, too.

On the Plus Side

For couples that have a solid relationship and know each other well, working together can be a dream come true. They are able to spend more time together, and share yet another important part of life with each other.

Sometimes, it's hard to compose a romantic love letter. For some of us, it's easy to pour out our feelings. But others would rather bury themselves than have to show their emotional side. Hey, it takes practice. Here are some tips!

Romance, passion, lust
"Love makes me write what shame forbids me speak."
Robert Herrick, "What Shame Forbids to Speak"

Ah.... Love letters. Have you ever received an old-fashioned hand written love letter? Or have you ever written one? Have you ever received a love letter that made your heart melt? That made you breathe harder? That made you cling on to every single word? These days it's rare to receive a romantic love letter likes that, especially one that speaks from the heart. Writing love letters is a lost art. It's like painting a portrait of a beautiful woman on canvas. A painter must carefully capture every detail or feature of the woman or the moment is lost.
