Hi,
I'm not surprised she is tired and out of breath, she must have started working since about 2011, when she first arrived in Cardiff when she was about 19 with her friend Daphne. Carla was young and pretty back then, but 7 years of working non stop would probably take its toll in all ways. A shame really, as see was really sweet back then, but spoke very little English, but very friendly.
I imagine the other girls in the original Cardiff group she arrived with in UK probably decided to retire when they burnt out, but it seem Carla is carrying on.
Must be quite tough keeping enthusiastic after years of working,
Rich
