Bryan Johnson, an American biohacker and entrepreneur, has authored an intimacy manual for his young adult son, aiming to fill the educational gap regarding sexuality and intimacy. Johnson pointed out that many young adults lack knowledge about making love and understanding the nuances of physical touch. He explained that the speed of touch can affect how intimacy is perceived, stating, 'If you move it slower than 3 cm per second, the nerve fibres say, 'I feel intimate.'' This manual has been likened to a '50 Shades of Grey, longevity version' by some readers. Experts, including psychologist Shravani Bongu, emphasize the importance of parents discussing sexuality openly with their children to prevent them from seeking unreliable information. Bongu suggests that parents should create a comfortable environment for discussions, maintain open lines of communication, and be direct in their responses to questions. She also highlights the need for educating children about internet safety and media literacy in today's digital age. Overall, Johnson's initiative and expert advice aim to foster healthier conversations about intimacy and relationships among young adults.
