I just thought that if I don't jump in, then this person can die in a matter of seconds."Thosago promptly dived into the pool and lifted the man's head above water."With no hesitation, he jumped in, he was very brave," the gym's general manager Shanice Butcher told News24.Almost immediately, Thosago was joined by several other staff members who jumped in and helped to get the man out of the pool.
