Speakout Advanced p 58. Getting Married. Extra Joke

Jack, aged 92, and Gill, aged 89, were excited about their decision to get married.
They visit the local pharmacist and say, “We are about to get married. Do you sell heart medication?” Yes, was the answer. “How about pills for rheumatism /ˈruːmətɪzəm/ and arthritis /ɑːˈθraɪtɪs/?” Yes, of course. “And suppositories /səˈpɒzətriz/ and incontinence pads?” We sell all of that. “Sleeping Pills, Indigestion /ˌɪndɪˈdʒestʃən/, Heartburn, medication for the onset (beginning) of Alzheimer's /ˈæltshaɪməz/?” Certainly. “What about Zimmer frames /ˈzɪmə freɪmz/, wheelchairs and canes?” We have all speeds and sizes, sir.
