Going back and doing it the same again
If I could change the time again, I'd go back to July 4yrs ago to the Sunday evening sitting on my couch watching TV when I thought I had bad heartburn but this time I'd call an ambulance. Would have saved my wife and kids the trauma of seeing me dead
If I couldn't change anything then I'd go back to my early 20's and spend another summer in Mexico working as a snorkeling instructor at a Club Med
or spending my childhood summer evenings after school and weekends snorkeling
