At what height is ozone no longer a problem for our health ? <| sep |> Extra from learninLearnin here . As you know , I have no doubt that the head blow came any where from 15 minutes to one hour after JBR consumed pineapple . After head blow , IMHO , peristalsis bowel contractions which push the food along stopped with the onset of shock . I use the 15 to 60 minute window as a liberal window to allow for slight variations among people . It could have come within minutes of eating as my test proved . The ME reported seeing dust and lint on the bottom of JBR ' feet when inspecting her at the home before the body was removed . She didn ' t get that lint on her feet after the head blow so I believe she was standing on a dusty floor when the head blow was delivered . I believe the dust would have come off if she had picked it up previously and then walked around before being struck . Now , was the kitchen , dining room floor that dusty ? Possibly , but I opt for a basement room where little cleaning was done . So , I believe she ate pineapple , with Burke , in dining room and within 30 minutes or so , they found themselves in the basement where the blow was struck . I have another experiment in mind where I will use a 6 y . o . and it will not require any radiation . I will prove that pineapple will be in the duodenum , of a six year old , within minutes
