Been getting into long distance biking more recently and a lot of people use ‘gels’ for energy which are pretty much honey, salt and water - or sometimes things like ‘ketone’ energy drinks etc.

Gels seem like the peatiest option here but I want to experiment more/make my own, what else should I be adding beyond just the honey salt and water you think?

One broader question on cancer, following the discussion, would be methods for identification of cancer / detection. Biopsy seems to be a no-go overall given the stress it induces to the body, often promoting a cancer.

Does liquid biopsy (blood tests) present an option? Below post seems that if you are looking for genes, then not. If not looking for genes, what are we looking for then?

@Peatly said in cancer:

A blood test to look for fragments of DNA in the bloodstream

“She was offered a blood test, also described as a "liquid biopsy" which looks for fragments of DNA which have broken off tumours and are in the bloodstream.

This so-called "circulating tumour DNA" revealed that Kat's cancer growth was being driven by a mutation in the ALK gene.”

I won't state the obvious

This story was published hours before the announcement that the other Kate has cancer.
