I really wonder about 6) obesity because my doctor never told me I am risk of dying (note i am overweight.)
this is about many factors associated with obesity
how well oxygen can get around your body.
EG
if your so obese that just getting out of bed you breathless.. you are gonna have it severe 10/10
if you walk around ur house fine but walking around your park is a strain 9/10
if you get breathless jogging and it takes more then 10mins to catch your breath 8/10
risk number goes down the less trouble you have
as for oxygenation when sat down
if your extremities(hands and feet) go numb/pins and needles/cramps from just not moving. 10/10
if your limbs go numb/cramps from prolonged crossing legs/arms 8/10
if you get numbness/cramps from exercise. 8/10
..
basically if just overweight but never really get breathless in your day to day the risk is far far lower then someone that cant even put their socks on without getting exhausted.
there are other factors at play like how well your body can function generally. like metabolising energy.
so if you get tired doing small tasks thats a risk. but if you can walk to work, do work, come home. less risk
if you bruise easily or things dont heal fast. thats a risk as its a sign your body doesnt create cells/repair fast
if you dont urinate/bowel movement regularly thats a risk as its a sign your organs are not 100%
its never a true/false/yes no binary option. its a factor of a number of risk amounts that can add up
obesity is not just extra weight. its extra weight for your heart and lungs to handle. its also the strain on your organs. its also the bad diet for your organs. and also the extra body mass that requires more energy/oxygen just to continue existing
