I dont see why people would stop watching her due to being 27??? I do think she is far more capable than she makes out, and i hate the food waste. She seems to still have problems with eating, and finishing meals (never on camera) which is both concerning and annoying.
She had a bf (or gf who knows) at uni as she talked about bumping into an ex once. At least she is less likely to end up a divorced single parent by 30 if she is careful about being clear about what she wants rather than racing to get married (to anyone) by 27 and have a baby. Personally can't think of anything worse.
I really did enjoy taz and moon vlogs and travel vids. She rents her own place in london, makes (somehow) a good income off youtube, has friends, reasonably close family and has a law degree, this are achievements imo.
Maybe a cooking course series next, she could recreate what she learns each week.
