Good posture is an easy and very important way to maintain a healthy mind and body. When you practice correct posture, your body is in alignment with itself. This can alleviate common problems such as back or neck pain, headaches, and fatigue.
There are roughly 500 billion galaxies in the universe, meaning there is somewhere in the region of 50,000,000,000,000,000,000,000 (5Ã1022) habitable planets. Iâll leave you to do the math on whether one of those 50 sextillion planets has the right conditions for nurturing alien life or not.
There are possibly 80 billion galaxies in the universe, so that means that there are about 4Ã1068 Ã 8Ã1010 = 3Ã1079 hydrogen atoms in the observable universe. But this is definitely a lower limit calculation, and it ignores many possible atom sources such as intergalactic gas.
