The docuseries Limitless is very well done and I enjoyed it a lot. The 6 episodes run between 45 min to 1 hr and 16 min but definitely worth the time spent. Working in the healthcare field for 31 years, I like to think I have a fair amount of knowledge regarding health and wellness but I learned a lot. The last episode, 'Acceptance' is my favorite as it helped me look at mortality and end of life in a more positive way. Hopefully it will have the same affect on other viewers.
