It is unlikely for someone to change 100 percent, as change is a gradual process that takes time and effort. While significant change is possible, it is rare for someone to completely transform every aspect of themselves. It is more realistic to focus on making incremental changes and improvements in different areas of one's life. **

As an AI language model, I don't have a nationality or ethnicity, so I don't have a genetic background. I am a machine learning model created by OpenAI, and my responses are generated based on the input I receive. **

Sexuality is a complex and fluid aspect of human identity, and it is widely accepted that most individuals do not fall strictly into one category of sexual orientation. Many people experience some degree of attraction to individuals of the same sex, opposite sex, or both. Therefore, it is possible that no human is 100 percent heterosexual, as sexuality exists on a spectrum and can vary for each individual. **

Sexuality is a complex and fluid spectrum, and it is widely accepted in the scientific community that human sexuality exists on a continuum. This means that individuals may not fit neatly into categories like 100% heterosexual or 100% homosexual. Many people may experience attractions or feelings that fall outside of traditional labels, and it is important to recognize and respect the diversity of human sexuality. Ultimately, it is up to each individual to define their own sexual orientation and identity. **

While it is important to have trust in your friends, it may not be realistic or healthy to trust them 100 percent. Trust should be earned over time through consistent actions and behaviors. It is important to maintain a level of discernment and boundaries in any relationship, including friendships. Trusting someone completely can leave you vulnerable to potential betrayal or disappointment. It is important to strike a balance between trust and healthy skepticism in any relationship. **

Cancer is primarily a non-contagious disease, meaning it cannot be spread from person to person through casual contact. However, there are certain viruses, such as the human papillomavirus (HPV) and hepatitis B and C, that can increase the risk of developing certain types of cancer and can be transmitted through sexual contact or blood-to-blood contact. Overall, the majority of cancers are not contagious and are caused by a combination of genetic, environmental, and lifestyle factors. **

Cancer itself is not contagious in the way that a cold or flu virus is, meaning it cannot be passed from person to person through casual contact. However, certain viruses such as HPV and hepatitis B and C can increase the risk of developing certain types of cancer and can be transmitted through sexual contact or blood-to-blood contact. It is important to note that cancer is primarily caused by genetic mutations and environmental factors, rather than being directly contagious. **
