A system for detecting and logging the occurrence of flatulence comprising: a gas collecting device mounted underneath a chair for receiving flatulence released by a user sitting on said chair; a hydrogen sulfide sensor located within said gas collecting device and connected to said gas collecting device and operative to detect existence of hydrogen sulfide gas in said flatulence; characterized by: a frequency detector connected to said hydrogen sulfide sensor for detecting frequency of occurrence of flatulence in a selected period of time; a duration sensor connected to said hydrogen sulfide sensor for detecting duration of each occurrence of flatulence; a logging device connected to said frequency detector and operative for receiving an event signal from said frequency detector indicative of number of times flatulence occurring in said selected period of time; and said duration sensor also forwarding a duration signal to said logging device indicative of the length of time of each occurrence of the flatulence; a removable bacteria cartridge connected to said hydrogen sulfide sensor and a bacteria check sensor connected to said removable bacteria cartridge and operative for indicating whether said removable bacteria cartridge is to be removed for cleaning to remove accumulation of bacteria in said removable bacteria cartridge; a display device connected to said logging device, said display device and said logging device being operative by a user control panel connected to said logging device and said display device to display entries of said occurrence of frequency of occurrence of flatulence and duration of occurrence of each flatulence in said selected period of time for representing body cells signaling activity indicative of health condition of said user. a gas collecting device mounted underneath a chair for receiving flatulence released by a user sitting on said chair; a hydrogen sulfide sensor located within said gas collecting device and connected to said gas collecting device and operative to detect existence of hydrogen sulfide gas in said flatulence; characterized by: a frequency detector connected to said hydrogen sulfide sensor for detecting frequency of occurrence of flatulence in a selected period of time; a duration sensor connected to said hydrogen sulfide sensor for detecting duration of each occurrence of flatulence; a logging device connected to said frequency detector and operative for receiving an event signal from said frequency detector indicative of number of times flatulence occurring in said selected period of time; and said duration sensor also forwarding a duration signal to said logging device indicative of the length of time of each occurrence of the flatulence; a removable bacteria cartridge connected to said hydrogen sulfide sensor and a bacteria check sensor connected to said removable bacteria cartridge and operative for indicating whether said removable bacteria cartridge is to be removed for cleaning to remove accumulation of bacteria in said removable bacteria cartridge; a display device connected to said logging device, said display device and said logging device being operative by a user control panel connected to said logging device and said display device to display entries of said occurrence of frequency of occurrence of flatulence and duration of occurrence of each flatulence in said selected period of time for representing body cells signaling activity indicative of health condition of said user. a frequency detector connected to said hydrogen sulfide sensor for detecting frequency of occurrence of flatulence in a selected period of time; a duration sensor connected to said hydrogen sulfide sensor for detecting duration of each occurrence of flatulence; a logging device connected to said frequency detector and operative for receiving an event signal from said frequency detector indicative of number of times flatulence occurring in said selected period of time; and said duration sensor also forwarding a duration signal to said logging device indicative of the length of time of each occurrence of the flatulence; a removable bacteria cartridge connected to said hydrogen sulfide sensor and a bacteria check sensor connected to said removable bacteria cartridge and operative for indicating whether said removable bacteria cartridge is to be removed for cleaning to remove accumulation of bacteria in said removable bacteria cartridge; a display device connected to said logging device, said display device and said logging device being operative by a user control panel connected to said logging device and said display device to display entries of said occurrence of frequency of occurrence of flatulence and duration of occurrence of each flatulence in said selected period of time for representing body cells signaling activity indicative of health condition of said user.
