To ensure a healthy and happy life, it is important to take care of the body at all times. Most people focus on physical exercise and diet, but often forget that mental health is very important. Ironically, the exact same things that contribute to physical health, like exercise and diet, also contribute to mental health.

Mental exercise is very important. But don’t imagine your brain doing push-ups or crunches. Activities like crossword puzzles, learning languages, or even simple everyday interactions with other people, all are mental exercises.
Music and games also help a lot. These activities stimulate brain cells and also provide a sense of accomplishment when they are done.

For most people, the obvious choice is counting the major triangle, then counting off the smaller triangles. That is where it gets confusing. There is the temptation to count one triangle more than once.
What is your answer and how sure are you that it is correct?
There is actually a right answer
The simplest solution to this puzzle is to count all the smaller triangles, starting from the top of the big triangle, and then working down to the bottom.

Finally, add the big triangle to the number you get. The total number of triangles should be 18. If that was your answer, congratulations. And if it wasn’t, you still did well. Your brain has gotten a good workout in the process.
