Every hour of Connie Colgans day is carefully choreographed. Rising at 5:30 a.m. she prepares for a marathon of waking, dressing and feeding her six children before chauffeuring the eldest four to school. Sean and Conor, 3 years old and 19-months respectively, wreak havoc at home as their mother tidies, does laundry, cooks and then ventures out again to ferry the kids to swimming, Irish dance, piano and gymnastics classes. Gruelling as her schedule is, Colgan is adding another routine - she has enrolled her family in an ambitious new health study that will rank her brood among the most biologically characterized humans on Earth.
