                        <p>Consciousness evolved in stages, starting with basic survival responses like pain and alarm, then expanding into focused awareness and self-reflection. These layers help organisms avoid danger, learn from the environment, and coordinate socially. Surprisingly, birds show many of these same traits, from subjective perception to basic self-awareness. This suggests consciousness is far older and more widespread than once believed.</p>

                        <p>Natural killer cells act as the immune system’s rapid-response team, but the stress of anxiety and insomnia may be quietly thinning their ranks. A study of young women in Saudi Arabia found that both conditions were linked to significantly fewer NK cells—especially the circulating types responsible for destroying infected or abnormal cells. As anxiety severity increased, NK cell levels dropped even further, suggesting a stress-driven weakening of immune defenses.</p>
