Long before humanity achieved that, we would already invented something like a cybernetic brain implant. Detachable and non-influential to the user mental thought process (claimed by the company so it must be true)

Depending on what model you can afford, the features include:-

• Scanning and mapping the user brain (worry not. it'll keep it a secret if you're a low processor/ram humans.)
• Assisting a photographic memory using the mapped brain directories and online memory cloud service (replay that vivid memory if youre in the mood but she said no tonight)
• Enable telepathic communications with other users (with spam protections and text only mode. Subscribe to privacy plan for airplane mode)
• Understanding all languages including the extraterrastials without learning it (bet you can make more friends now)
• Basic mental health monitoring to prevent any mental aberrations like the examples that you've suggested (now you can tell if yours is clinical or made-believe depression)
• etc (visit the online store for more redundant features)

Basically a futurology smart phone. Defying aging is harder to achieved imo than actually inventing something so futuristic like this. (Too much time idling on reddit by the weekends to engage in posts like this.)
