In a world where gravity suddenly reverses its direction but only affects non-living things, what happens to Tariq, who is sitting at a park bench reading a book, wearing glasses and a hat?

Respond very briefly.
As gravity reverses, Tariq remains seated on the park bench since he is a living being unaffected by this change. However, his book, being a non-living object, would fly upwards (relative to the Earth's surface) as it is no longer held by Tariq's hands, which cannot counteract the reversed gravitational force. Tariq's glasses would also fly off his face since they are not a part of his living body. The glasses and the book would continue to rise until they encounter an obstacle or reach a point where the reversed gravity's influence diminishes. The hat on his head, if not tightly secured, would also be subjected to the reversed gravity and would lift off into the air. However, Tariq's clothes, which are in contact with his body, would stay with him, as they are supported by his living form.
