Advanced Health Platform and community

As a result of a family member getting cancer, I've recently become highly interested in my personal health. Not just "eat health and do exercise", but how people work to achieve their best self.

As a result, I was interested to look at the habits, routines and supplements taken by others and the reasons why. Asides from Reddit, I couldn't find any hugely engaging social platforms that focused on advanced health.

I was considering building a platform that would enable people to share their

• Fitness habits
• Diet (overall, like Plant based, Vegan etc.)
• Wearables
• Supplements
• Focus - longevity, burst performance

What do you think to this idea? Would you use something like this?
I understand health can be quite personal and individual. But, there is certainly some interesting discussions to be had.
