First, Malawi is one of the poorest countries in the world. Brother Welosi is dressed quite decently in the midst of endemic poverty (probably second-hand clothing imported from wherever). He has a "beard", but a lot of that goes with age in Southern Africa. He actually looks the better for it since said "beard" matches what hair is left on his head. The sister is not wearing a hat - it's a "head scarf" commonly worn by women of all ages throughout sub-Saharan Africa.
Please, always remember the context. More than a third of humanity only manages to scrape by and cannot afford certain "luxuries" considered nothing by those who can. There is no point mocking the poor who only happen to have been born where surviving is more a matter of luck than anything else, or lampooning a person in whose shoes we've never walked even if, in our opinion, they are in the "wrong" religion. Oh, about that "knocked out" tooth? Were he in a society with affordable medical care and had the means, Brother Welosi would most likely have had that replaced. Overall, considering his "robust" looks, he's come a long way in a country where life expectancy at birth is 50.
