Interesting, since I turned 70 had been required to use a cane for years to get around. Three years ago at 85 I decided to start taking powdered Beets concentrate mostly Beet Power (brand) and since then don’t need a cane. Am also now taking Tonic soda and zinc supplement once a day.
The “tonic” being quinine from the tree bark source the discovery of which for use in malaria, made the British Empire possible in the malaria stricken areas of the world.
It was Peruvian natives who used he bark of the Cinchona tree in an extract to fight chills and fever in the seventeenth century. The quinine drug goes all the way back to 1633, amazingly. Hydroxychloroquine, and chloroquine are both analogues of quinine.
The British invented the used of tonic/quinine fizzy water with GIN! (yes!) to enable their people to take the quinine daily. It worked. And... gin brought down the Empire so it is said.
