You may have been in the field too long if...

1) you've been listening to the BBC on the short wave for so long that you recognize the voices of all the news readers and can tell if they have a cold;

2) you stopped taking your malaria meds so long ago you can't remember the dosage;

3) you file your nails with the same bastard file you use to sharpen your trowel and your machete;

4) Sunscreen? Ha, ha, ha, ha, ha, cough, snort. Oh, that? That's just a mole;

5) You intuitively recognize whether the GPS coordinates are correct in DMS, decimal degrees, and UTMs;

6) You can spot a sherd on the side of a dirt road while driving by at 50 kph;

7)  You're on a first-name basis with every farmer and hunter in the district/state/department/canton/province;

8) Your athletic socks have evolved to the point that they could pass a Turing test;

9) trenchfoot is a frequent topic of casual discussion;

10) you don't even think about TV any more; and, drum roll please,

11) you've forgotten what it's like not to have diarrhea.
