Injury is another common reason that people develop lower back issues.  Protect your back while lifting items by using the proper methods of lifting that avoid back strain. This is important even when you are young, as minor injuries that do not affect you immediately may make you more susceptible to more serious injuries later on. Approach an object you intend to lift and stand as close as possible to it. Spread your feet apart to provide yourself a wide base of support. Essentially, position yourself so that you're able to bend at your knees and grip the object either between or just in front of your feet.  Never position yourself in a way that will require you to bend at your waist or at your back. After safely positioning and gripping and object, tighten and maintain the flex of your stomach muscles as you lift an object.  Always raise and lower an object straight up and down, holding it close to your body and using the muscles in your legs. Again, do not bend or twist when lifting, lowering, or carrying a heavy item. When setting something down, do so with a squatting motion, keeping your back straight and using the muscles in your legs to bare the load. Get help lifting anything that you are not absolutely certain you can lift safely on your own.  If an item is awkwardly shaped, or is heavier than items you commonly lift with ease, have someone else help you lift it.  Whenever available, use dollies or other tools and machines to help you move heavy objects.

summary: Prevent back injuries by lifting carefully. Position yourself closely to heavy objects. Lift and lower straight up and down. Get help lifting dangerous objects.

Ball mason jars were produced for many years with the year 1858 printed on them, but this is no indication of the age of jar itself. Rather, 1858 is the year that John Mason was granted a patent for his mason jar design, and the Ball company used this patent year on many jars. This was another patent date that was printed on many mason jars, and that has no bearing on the year of production. In fact, Ball used this patent date on their jars well into the 1930s, so this year cannot be used to accurately date a Ball jar. Many Ball mason jars have a number printed on the bottom of the jar, but this is a mold number that does not indicate the year of production. Rather, the mold number tells you where the jar was positioned on the glass-making machine that was used to produce it. Mold numbers are generally a number between zero and 15, and they’ll sometimes have a letter included as well.
summary: Ignore the 1858 patent year. Ignore the 1908 patent date. Ignore the mold number on the jar.
