observations while in the hospital

i have never been in the hospital before in my entire life. this past week i was in the hospital all week from monday to thursday; and let me tell you that saying "you never sleep in a hospital", could not be more on point. i have never been so tired i kept being woken up every hour even in the middle of the night. i was very interested to see the evolution of technology in science. old traditional ways like getting a temperature and reading my blood pressure all include technology now. i remember when i was little the doctor used to use a thermometer and put it under my tongue, now they have a dial that runs across my face and behind my ears that digitally reads a temperature. i guess i am just a little dated, and i hardly ever go to the doctors or pay attention to minor details like such but i had a little more time on my hands and i was intrigued.
