Diving in Remote Areas

Diving has inherent risks. The human body was not designed to be underwater, and drowning, decompression illness, barotrauma, hazardous marine life injuries, and preexisting health issues all require an emergency response. Diving in remote areas introduces additional risks, especially access to medical care.

From Sea to Space

Underwater environments simulate the conditions of space exploration and allow NASA to test equipment, perform research, and prepare for future missions in extreme settings such as the moon or Mars. Being underwater replicates the isolation, confined spaces, and limited resources astronauts experience in space.

Canceling for Cancer

I always get DAN Trip Insurance for overseas trips, which gives me peace of mind should the unexpected happen. There is a modest upfront payment based on the total trip costs and your age, so I considered skipping it for a Raja Ampat trip since I’ve had many trips without having to file a claim. I’m glad I chose otherwise.
