Yes: Everybody has something. There are no perfect adults, and no perfect children. Sooner or later, everybody gets sick. Luckily, our bodies have miraculous self-healing powers, and we generally get well. For the unlucky ones among us... well, those don't make it. The lesson here is to do kind and meaningful things each day, while we are still in good health. ...Read more
Simple evolution: In a village far, far away, and a long time ago, some humans wanted sex. Some humans didn't want sex. As the years went by, the humans who wanted sex got pregnant more often, had more children, and became the great majority of the population. The humans who didn't want sex didn't have many children, so those carrying the "don't want sex" trait became a smaller and smaller part of the population. ...Read more
Density: Hi. I think you're wondering about density, not weight. After all, a pound of fat, pound of feathers, & pound of lead all weigh the same, but their densities differ dramatically. The density of human fat is about 0.9 g/ml, whereas the density of human muscle is about 1.06 g/ml. Does that help? Try to understand mass, volume, density, and weight. Physics is fun! Good luck! ...Read more

In a way: Forever is a long time, but cells can be made to turn off their natural cycles which would cause them to die sooner. Cancer cells often develop this trait and thus outlive their host (temporarily). Read the immortal life of henrietta lacks for a good layman's explanation of this process. ...Read more
Depends.: I am assuming you are talking about the half life of a drug. A drug with a 25 hours half life means that after 25 hours, the blood concentration of the drug will be halved. So at hour zero it's 100%. At 25 hours, the concentration is 50%. At 50 hours, it's 25%. At 75 hours, it's 12.5% etc. Please note that using half lives is an oversimplification and doesn't always correlate with drug effect. ...Read more
Yes: It has been shown that crustaceans, which are somewhat close to many insects on the evolutionary tree, have nociceptors, or neurons/receptors that sense pain. While we can not be sure if insects can sense pain, it is likely they have some primitive pain sensation. ...Read more

I am not sure what you are truly asking. Are you asking us about coffee consumption? Or about one single product that contains caffeine.
Either way there are very little scientific answers to the question about whether caffeine is harmful to health. There are lots of clues that there are some health benefits to moderate use of caffeine, but the science is not conclusive. ...Read more

Males are much smaller ; cling to a female's legs. They are often seen on beaches during a high tide ; can be observed hopping about ; making a high pitched sound. At daytime they are usually buried in the sand. ...Read more
