Traditionally, drill rods were made from steel, which was strong but heavy and prone to wear and tear. This limited their reach and required frequent replacement, leading to increased downtime and costs. However, with the development of advanced materials like high-strength alloys and carbon fiber composites, mine extension drill rods have become lighter, stronger, and more durable.

While groupthink and fan culture can coexist harmoniously in many cases, there are also potential negative consequences. For example, when fans become too obsessed with their idols, they may lose touch with reality and engage in harmful behavior, such as excessive spending or cyberbullying. Similarly, when fans of a TV show or movie become too defensive of their version of the story, they may reject valid criticisms and prevent meaningful conversations from taking place.

The relationship between settler groups and indigenous peoples was often fraught with tension and conflict. Settlers often saw themselves as superior to indigenous peoples and sought to dominate and exploit them. This led to violent conflicts and forced displacement, as well as the destruction of indigenous cultures and ways of life. In some cases, settlers also engaged in genocidal practices against indigenous peoples, leading to the loss of countless lives.
