proteins!
speaking of that chicken or fish I heard that worms are actually quite healthy. They are full of protien and minerals...great for toning!!!
Perhaps offering to stow everyones cabin bags in the overheads would be great for working out those biceps/triceps....also another handy tip of advice open all the lockers with one arm then turn around and walk back the other way and use the other arm to shut them....great cardio workout and gets those arms burning!!!
As for the weather....it's summer in oz and seriously you know what i mean...it's beach time!!! Time to tan!!!
