The trait is known to cause significantly fewer deaths due to , especially when is the causative organism. This is a prime example of , evident by the fact that the geographical distribution of the gene (for hemoglobin S) and the distribution of malaria in Africa virtually overlap. Because of the unique survival advantage, people with the trait become increasingly numerous as the number of malaria-infected people increases. Conversely, people who have normal hemoglobin tend to succumb to the complications of malaria.

More maglev trains are expected to come in the areas of India, China and even the US in the future decades. The Maglev trains and Hyperloops will expectantly make mid-distance travel fast, calm and advanced.
