Is it possible to remove the digestive system and get only intravenous feeding as nutrients? This has several pros:
1)no need to eat, eating is stressful for your body
2)more productive life, since you don't lose time doing a trivial task as eating and don't feel tired because your digestive system is working after a meal
3)body weights less
4)no bad breath since your mouth is linked only to your lungs
