Here’s an Optimistic Savings Chart

Retirement grid

Retirement is a dream too far away for people to think about. We’re all really bad at thinking about the future and we often don’t want to think about money. Four Pillar Freedom put together the early retirement grid to address these concerns, and indeed retirement is something you can achieve. As with most issues in our society you can start making a positive impact on the world by buying less and reusing things more.

The sweet spot of the grid is found in the line of light yellow and green squares that cut through the middle. Each of those squares is in the 16 to 28 years range. They represent how many years you would need to work if you saved between 30% and 50% of your after-tax income. For many people, saving that much is a tough but realistic goal.

Considering the average person works for over 40 years, getting that number down to 28 is no small feat! That represents 12 extra years of your life where you get to do what you want, when you want, on your own terms.

$3 Wound Healing Device Saving Lives in Haiti

A student at MIT has created a device that helps people heal after severe wounds that costs a fraction of what commercial options cost. The device is a portable version of the negative-pressure devices that accelerates wound healing and reduces the frequency that bandages need to be changed. Commercially available devices cost about $100 and require a lot more energy than the MIT designed $3 device.

Negative-pressure devices, which act like a vacuum over the bandaged wound, have become a central part of wound therapy in the United States over the last decade. They speed healing up to threefold, depending on the type of wound, and in some cases eliminate the need for plastic surgery or skin grafts. A number of commercial versions are available in the U.S. and are used to treat burns and chronic wounds such as bed sores or diabetic foot ulcers. While scientists don’t exactly know why this treatment accelerates the healing process, it likely helps by removing some of the fluid and bacteria that accumulates at the injury site and by increasing blood flow to the wound. The pressure itself may also help healing by bringing together the edges of the wound and delivering mechanical pressure, which has been shown to spur cell growth, says Dennis Orgill, a surgeon at Brigham and Women’s who was not involved in the project.

Existing devices are often heavy, about five to 10 pounds, and require an energy source to create the vacuum, making them difficult to apply in disaster settings. Texas-based KCI, the leading maker of negative-pressure machines, has a portable version that’s battery powered, but it costs approximately $100 per day to rent. A number of companies are working on even more portable versions, say Orgill.

Six Good Things That Pay for Themselves

Being a little greener and a little richer is really easy with these six items that pay for themselves within a year by helping the environment.

5. Programmable Thermostat
Having a programmable thermostat is the easiest way to lower your heating and cooling costs. And having the house temperature right where you want it every hour of the day isn’t bad either. You can find programmable thermostats as cheap as $20 – at that price, it would probably pay for itself many times over in a year.
