Long walks help in delivery

I've jus learned from my friend Tat walking actually helps a great deal in her delivery . She used to walk all the way along the Singapore - Johor bridged to get to work twice a day . And yes we'll be thinking she got to be mad .. But the fruit is all her 5 kids were delivered without a single pain... All she felt was sone tickling n yeah she felt it's time to go hospital. Hmmm hard work always have it's one sweet benefits at the end if the day :)
