Why does the author use different tenses? Dr Scott SUGGESTED women tend to suffer more when pretending to be happy because they are expected to be more emotionally expressive than men. Therefore, faking a smile while feeling down is more likely to go against their normal behaviour and cause more harmful feelings. Although, 'deep acting' seemed to improve mood in the short-term, Dr Scott SAYS it's not a long-term solution to feeling unhappy. He SAID: "There have been some suggestions that if you do this over a long period you start to feel inauthentic Why does the author use the simple past tense 'SUGGESTED' in the first paragraph, use the simple present tense 'SAYS' in the third paragraph, and then use the simple past tense SAID in the last paragraph? Thank you!
