Retired Navy officer, Dr Joseph Dituri has set a new world record for living underwater for the longest time as he carries out medical and ocean research and conducts online classes and broadcast interviews from his digital studio.
Dr Dituri, a renowned professor at the University of South Florida who goes by the nickname "Dr Deepsea," recently spearheaded an ambitious underwater expedition dubbed Project Neptune 100.
The ultimate goal of this initiative was to gain insights into how the human body copes with prolonged exposure to intense pressure in an aquatic environment.
"The curiosity for discovery has led me here. My goal from day one has been to inspire generations to come, interview scientists who study life undersea, and learn how the human body functions in extreme environments," he tweeted.
Dr Dituri broke the previous record of 73 days, two hours, and 34 minutes set by two Tennessee professors, Bruce Cantrell and Jessica Fain, at the same location in 2014.
From doing research work, and physical exercises using resistance bands and push-ups to eating a protein-heavy diet, including eggs and salmon cooked in a microwave, and taking an hour-long nap, Dr Dituri spends his days keeping himself engaged.
His research includes daily experiments in physiology to monitor how the human body responds to long-term exposure to extreme pressure.
While he loves to live in the deep sea, what he misses the most about being on the surface is the Sun.
