Heyas,
If you go:
Take DEET. The strong stuff, not the wussie stuff you get at "Outdoor City". Consider prophalactic malarial meds. Depending on where you go, you may need a Yellow Fever vaccination, which MAY make you ill on it's own, and is not recommended for older folks..
Wear long sleeves. SLATHER the bug repellant on.
Malaria or yellow fever is no joke. You DO. NOT. WANT.
