• Biohacking is the trend of optimizing your physical and mental health for longevity.

• I went to a biohacking event to test out the buzziest longevity technologies.

• From red light therapy to neurofeedback, not all remedies are created equal.

Don't be concerned, but I'm 24, and I'm already worrying about aging.

I religiously reapply sunscreen throughout the day and keep a ready supply of colorful roasted vegetables in my fridge (you did good, mom), but the San Francisco biohacking event I attended this month made me feel like a longevity fraud.

From neurofeedback to red light therapy, several technologies used for wellness were available — so, naturally, I tested everything I could get my hands on and observed the products I couldn't try. Some products proved immediately valuable, while others left me altogether confused.

As experts have told my colleagues on Business Insider's health team for years, the best way to protect our health long-term and boost our longevity is to nail the basics: eating a balanced, nutritious diet; regularly doing exercise we enjoy; getting enough sleep; and having meaningful relationships and purpose in life. Still, I couldn't help being curious about what the biohackers could offer me.

With price, overall benefit, and ease of daily use in mind, these are the longevity technologies that I actually found worth trying, ranked from least to most appealing.
