Yes, a 16g piercing can fit in an 18g hole. The gauge of a piercing refers to the thickness of the jewelry, so a 16g piercing is slightly thicker than an 18g hole. It may require some gentle stretching, but it is possible to insert a 16g piercing into an 18g hole. However, it is important to consult with a professional piercer to ensure that the stretching process is done safely and without causing any damage to the piercing or surrounding tissue. **

Consuming 18g of protein per kg of body weight is generally considered excessive and potentially unhealthy. The recommended dietary allowance for protein is 0.8g per kg of body weight, and consuming significantly more than this can put strain on the kidneys and liver. Additionally, excessive protein intake can lead to dehydration and an increased risk of osteoporosis. It's important to consult with a healthcare professional or registered dietitian to determine the appropriate amount of protein for individual dietary needs. **

The popularity of cycling or skiing can vary depending on the location and time of year. In general, cycling tends to be more popular in urban areas and during the warmer months, while skiing is more popular in mountainous regions and during the winter. However, it's difficult to determine which activity is followed more overall without specific data on participation rates in different regions and seasons. **

The excitement level of ice hockey versus soccer is subjective and can vary depending on personal preferences. Ice hockey is known for its fast-paced, physical nature with constant action and scoring opportunities. On the other hand, soccer is a more strategic game with longer periods of build-up play and intense moments during goal-scoring opportunities. Both sports have passionate fan bases and offer unique thrills, making it difficult to definitively say which is more exciting. **

It is highly unlikely that soccer will replace American football, basketball, baseball, and ice hockey as the most popular sports in the USA. These sports have deep-rooted cultural and historical significance in American society, and they have large and dedicated fan bases. Additionally, American football, basketball, baseball, and ice hockey have well-established professional leagues and infrastructure in the USA, which would make it difficult for soccer to overtake them in popularity. While soccer has been growing in popularity in the USA, it is more likely to continue to coexist alongside these other sports rather than replace them. **

Ice hockey is often perceived as more brutal than soccer due to the physical nature of the sport, which includes body checking and fighting. However, both sports have their own unique physical demands and risks of injury. While ice hockey may have more violent collisions, soccer players also face the risk of serious injuries such as concussions and ACL tears. Ultimately, the level of brutality in each sport can vary depending on the intensity of the competition and the actions of the players involved. **

The delivery time for a standard letter without priority, weighing approximately 18g, to Spain from the United States is typically 7-14 business days. By affixing $1.45 postage on the letter, it should cover the cost of international postage for a letter of that weight. However, factors such as customs processing and local postal service efficiency can affect the actual delivery time. **

Typically, a non-priority letter weighing around 18g sent to Spain with €1.45 in postage can take around 5-10 business days to arrive. However, delivery times can vary depending on factors such as the efficiency of the postal service and any potential delays in customs. It's always a good idea to check with your local postal service for more accurate estimates. **
