Revealing the 5 SECRETS that enabled Taylor Swift to perform 44 songs four nights in a row for three and a half hours during her Eras Tour- and the one thing she gave up that made millions of fans startled and REGRETFUL…K

She performs 44 songs from all her 10 albums over three and half hours at each of her Eras Tour concerts, all while undergoing multiple costume changes.

And with dozens of shows to go, many are wondering how Taylor Swift is going to survive her world tour.

In Sydney last week, the Cruel Summer songstress played four shows back-to-back across four nights – a total of 10 hours and 30 minutes – without showing the slightest ounce of exhaustion.

The pop megastar said she knew what she was facing before she embarked on the tour, and came very well prepared.

‘I knew this tour was harder than anything I’d ever done before by a long shot,’ she told Time magazine last year.
