We all know the stinging sensation and welling up of tears that comes from chopping onions. But why does this happen? In fact, the reason onions make us cry can be traced back to the soil.

Given on special occasions or simply to tell another person how much you care, flowers continue to be appreciated as gifts and for their beauty. Whether it is Valentine's Day, Mother's Day, or just an ordinary day, a nice floral bouquet is bound to bring smiles to its recipient's face. Yet while flowers are a great gift and add a splash of color, they also do much more for us. In fact, flowers help the environment around us in many ways. Flowers appear on plants, which themselves are beneficial to our ecology and environment. As is well-known, plants produce much of the oxygen in our atmosphere through the process of photosynthesis.

why do short sales take so long to close

RISMEDIA, September 8, 2010 Real estate professionals know that a short sale transaction can take months for it to be approved and closed. The reality is that short sales usually take three to four times as much as a regular sale to finally get to the closing. From the time the Realtor actually gets the property under contract to the time the lender approves, it could take anywhere from 30 days to six months, depending on how fast the borrower provides critical information for lender and Investor approval. Even then, you still have one more variable to account for which is the buyer waiting for all this time to get the contract approved by the lender. For this, setting the expectations is a key factor in any short-sale transaction. Buyers who make an offer on a short-sale property need to
