Ahem...lived a pretty healthy lifestyle with a lot of nutritional and workout maintenance. Still do. Worked when healthy, called in sick when sick. Left with 1200+ hours.

Unless one is exceedingly unhealthy, there's no practical way of recovering the allocated time without risking a policy violation and possible termination.

If it is a big issue to enough pilots, you guys need to trade the allocation for dollars, or extra time off as an optional contractual issue.
