Confucius said, “Without knowing the force of words, it is impossible to know men.” The largest part of your brain is the cerebrum (Suh-Ree-Bruhm). The folds and bumps give it an-other-worldly look. It’s divided into two halves and they are connected by the corpus callosum (Kor-Pus-Kuh-Loh-Suhm). It has a big job—helping you to do what you want to do; it controls memory, speech, intelligence, emotions and personality. We all use both sides of our brain, but the left side is adept at logic, organization, math, grammar and vocabulary; and, the right side of your body. </div> <div class="list__footer clearfix"> <a class="list__footer-readmore btn" href="/science/medical/articles/how-reading-rewires-your-brain/">Read more…</a> </div> </article> <article class="list__item post"> <figure class="list__thumbnail"> <a href="https://www.brighthub.com/science/medical/articles/second-hand-smoke-issues/"> <img src="/wp-content/uploads/2019/01/secondhand-smoke-700-300x225.png" alt="Second-Hand Smoke Issues"/> </a> </figure> <header class="list__header"> <h3 class="list__title post__title "> <a href="/science/medical/articles/second-hand-smoke-issues/" rel="bookmark"> Second-Hand Smoke Issues </a> </h3> <div class="list__meta meta"> <div class="meta__item-datetime meta__item"> <svg class="meta__icon icon icon-time" width="16" height="14" viewBox="0 0 30 28"><path d="M15 0C7 0 1 6 1 14s6 14 14 14 14-6 14-14S23 0 15 0zm0 25C9 25 4 20 4 14S9 3 15 3s11 5 11 11-5 11-11 11zm1-18h-2v8.4l6.8 4.4L22 18l-6-3.8V7z"></path></svg><time class="meta__text" datetime="2019-01-18T14:09:41Z">2019-01-18</time></div><div class="meta__item-categories meta__item"><svg class="meta__icon icon icon-category" width="16" height="16" viewBox="0 0 16 16"><path d="m7 2l1 2h8v11h-16v-13z"></path></svg><span class="meta__text"><a class="meta__link" href="/science/medical/" rel="category">Medical Science</a>, <a class="meta__link" href="/science/" rel="category">Science</a> </span> </div></div> </header> <div class="content list__excerpt post__content clearfix"> What is Secondhand Smoke? Secondhand smoke consists of the plume of chemicals and burning agents that come off the tip of a lit cigarette, cigar or pipe, including the smoke that is released from the mouth of a smoker.
