Problem: Article: Use a tape measure to find the dimensions inside of your cage. Write down the length of at least 2 sides if your cage is a rectangular shape. If you have an oddly-shaped cage, then measure each side of the base. Even if you used grid pieces that are 12 in (30 cm) long, measure the inside base since it may be slightly different in size. Coroplast is a waterproof material typically used to make lawn signs. Transfer your measurements onto a large piece of coroplast by drawing it on with a marker. Leave enough room for an additional 6 in (15 cm) on each side so you can fold them up into walls later on.  Coroplast can be purchased online or in stores that sell signs. If you can’t get a sheet of coroplast big enough for your cage, use multiple pieces and tape them together later on. Measure 6 in (15 cm) from the corner on each side of the coroplast, and draw a square on your coroplast. Use a utility knife to cut through the coroplast along the outline of the square. Remove the square completely so you’re able to fold the walls. Repeat the cuts for the remaining corners. Hold the straightedge along the bottom of your walls. Cut into the coroplast halfway to score the material. Score along each of your measurement lines so it’s easier to fold your coroplast into walls.  It doesn’t matter which side of the coroplast you score. Make sure not to cut through the coroplast entirely or else it could break the walls.
Summary: Measure the base of your cage from the inside. Mark the measurements onto coroplast, adding 6 in (15 cm) to each side. Cut out a 6 in × 6 in (15 cm × 15 cm) square from each corner. Use a straightedge and utility knife to score the bottom of the coroplast walls.

The older you get, the more important it is to actively work your mind. Doing puzzles is a great way to exercise your brain.  Brain teasers and word games are also excellent ways to train your brain. Try doing crossword puzzles or Sudoku. Download games onto your smartphone or tablet. Play chess, bridge, or other challenging board or card games. As you age, your cognitive speed slows down. Research shows that reading more can actually slow the mental aging process. Reading enhances your memory and increases your attention span. So grab a book, newspaper, or magazine and start reading! Try joining a book club. Your local bookshop or neighborhood library likely has a variety of groups you can join. Turn reading into a new social experience and meet new people. The act of learning is a great way to keep your mind sharp as you age. Continuing your education, learning new skills or pursuing a new hobby may help maintain  individual brain cells and fortify your memory.  Many people suggest trying to learn a new language, but you don't have to make it that complicated. Instead, try learning a new vocabulary word each day. To help, get a word of the day calendar or download an app to your phone.  You can also try learning a new skill. For example, maybe you've always wanted to learn how to knit. Teaching yourself a new hobby is a great way to keep your mind young. There are great benefits that come with socializing. Not only is it enjoyable, but it is good for your health. People who socialize regularly tend to have lower blood pressure and a decreased risk of diseases such as Alzheimer's.  Try scheduling regular activities with your friends. For example, create a dinner club that meets once a month. You can get together with friends and try new recipes or restaurants. Interact with your friends and family during your regular activities. For example, take your grandchild to the grocery store with you, or invite your neighbor to go on a walk. There are many ways to get more socialization into your day. If you are looking to meet new people, try going to classes at a yoga studio and striking up conversations with other people who are looking to better themselves. Book clubs, religious meetings, and gyms are also great places to meet other people and socialize.
Summary:
Do puzzles. Read more. Learn something new. Socialize more.
