The claim that red dye causes ADHD has been widely debated, yet, according to Snopes and other reputable sources, there is no conclusive scientific evidence directly linking red dye to ADHD. Research on this topic is ongoing, and while some studies suggest a potential correlation between artificial food colorings and increased hyperactivity in children, these findings are not specific to red dye nor do they definitively prove causation for ADHD. It's essential to note that ADHD is a multifactorial condition, influenced by genetic, environmental, and neurological factors. Parental concerns regarding food dyes and their children's behavior are valid, but attributing ADHD solely to red dye lacks scientific support. As always, consult healthcare professionals for personal dietary advice.

Fork oil grade refers to the viscosity of the oil used in motorcycle and bicycle suspension forks. It's crucial because it affects the dampening characteristics of the fork, impacting the ride quality and handling of the vehicle. The grade or weight of the oil is typically specified by the manufacturer and may vary based on the design of the suspension system and the intended use of the vehicle (e.g., racing, off-road, city riding). Common grades include 5W, 10W, 15W, and 20W, where the 'W' stands for winter, indicating the oil's performance at cold temperatures. It's essential to use the correct grade to ensure optimal performance and avoid damage to the suspension system. When considering a change in oil grade, it’s recommended to consult the vehicle's manual or a professional mechanic, as using a heavier or lighter grade can alter the suspension's behavior, potentially improving or degrading the handling and comfort.

If your base coat isn't curing, it could be due to a few reasons. The most common issue is improper lamp wattage or type for the product you're using. UV gels require specific wavelengths to cure, so ensure your lamp matches the product requirements. Additionally, expired or old polish doesn't cure well because the chemicals may have degraded over time. Another potential problem is the application thickness; too thick of a layer can prevent proper curing. Ensure your workspace is free from contaminants that might affect curing and follow the product instructions for the best results. Lastly, if you're using an LED lamp for a UV-only product (or vice versa), the base coat won't cure correctly.
