Narrative:

At 31000 ft I instructed first officer to go to cabin to inspect loose overhead panel. I did not immediately go to oxygen. First officer and I are reserve pilots. We were called to the airport with very little time to get there. Arrived 15 mins prior to scheduled departure. FAA air carrier inspector was waiting. Prepared aircraft (first officer arrived 5-10 mins prior to scheduled departure) and departed on schedule. Flight was short 57 mins atl-dab. On takeoff got warning lights for reverser lock problem. Climb out was busy avoiding broken cumulus clouds. Very busy talking to company reporting problem. At cruise flight attendant calls about overhead bin coming down on passenger. I instructed first officer to return to cabin and check. At this time I turned to watch FAA inspector go through the cumbersome process of getting out of jumpseat (B737). I should have immediately donned my oxygen mask. First officer had unbuckled his seat belt, turned sideways and also was watching FAA inspector. At this point inspector advised me to go on oxygen. I also had not flown for 3 weeks and first officer had not flown for 5 weeks. It was a very fast paced day with a lot of distrs and a slightly rusty crew.
