sure they do.
but even discarding his claims, the 24-hour observation period without food/water is still amazing. the docs did scans on his organs, brain, and blood vessels, as well as tests on his heart, lungs and memory capacity. all good/safe range. he's perfectly healthy. results from DNA analysis, molecular biological studies and tests on his hormones, enzymes, energy metabolism and genes will be released when they get the results.
wonder if he lost weight? he shouldn't have if his claims are true. another test on him would be very interesting, if he agrees to it; a longer one, with extensive test before, during and after. and surveillance 27/7 of course.
not being gullible, i'm very open minded is all.
