As I said earlier, the lightning is directed in such a way as to capture the age of the speakers on their faces, their faces are weathered, wrinkled and aged in general. The lighting is also warm and natural, representing them as elderly and happy people. This elicits pity from the audience as he is visibly old and nearing the end of his experience on Earth. Also at the start of the advert one of the elderly ladies says "stay young", this evokes a feeling of compassion towards her due to the fact that she is talking to a young person.
