In addition to protecting the bearings from external contaminants, hub dust seals also help to retain the lubricant that is essential for proper functioning
. As dust and dirt particles infiltrate the hub, they can mix with the lubricant and form a gritty paste that can accelerate wear on the bearings. By keeping the hub sealed tight, the dust seal ensures that the lubricant stays clean and free from contamination, thus extending the life of the bearings.However, it is important to acknowledge the overwhelming evidence surrounding the health risks associated with smoking. The World Health Organization (WHO) estimates that smoking causes over eight million deaths each year, a staggering statistic that cannot be overlooked. The dangers of smoking extend beyond the smoker; secondhand smoke poses serious health risks to those around them, particularly to children and pregnant women. Thus, the very idea of being a good smoker is complicated by the ethical implications of smoking in public spaces and the potential harm to others.
