       | So telomeres shortening has a useful purpose in preventing
       | runaway cell division right? So wouldn't artificially increasing
       | their lengths increase cancer incidence, unless combined with
       | other interventions for fighting cancer?

         | "The HBOT protocol was administrated in a Multiplace
         | Starmed-2700 chamber (HAUX, Germany). The protocol comprised of
         | 60 daily sessions, five sessions per week within a three-month
         | period. Each session included breathing 100% oxygen by mask at
         | 2ATA for 90 minutes with 5-minute air breaks every 20 minutes.
         | Compression/decompression rates were 1 meter/minute. During the
         | trial, neither lifestyle and diet changes, nor medications
         | adjustments were allowed."
