I’d challenge you to find a study or research that corroborates the theory that cargo pilots die early. The only studies that are even close are graveyard shift workers. They work upwards of 22-25 night shifts a month. A typical freight dog probably works 9-11 per month with a two to three hour nap in the middle and probably averages six to eight hours in a 24 hour period.
Make sleep a priority and get some exercise in at the hotel. Problem solved. But seriously, do some due diligence and separate the myth from reality.
