Why so many people eat junk food?

The reason why people eat junk food is because it tastes good and its cheap. I for one used to love eating junk food every day. I would usually eat chips, pizza, burgurs and drink soda while sitting down and watching tv or playing video games. It soon became a very bad habit for me, I was gettng fat and lazy and still hungry for more junk food. I soon came to realized that this has to stop, I couldn't walk up the stairs without breathing heavily and taking minor breaks along the way also my blood pressure jumped up to second level hypertension . So I decide to stop eating junk food and work out more often, atleast twice a day. Now I'm a bit more heathier than I used to be, even thought junk food can be very addicting you got to let it go, I learn that that hard way.

Should unapproved drugs be made available as a last resort to patients with conditions for which conventional treatments are known to be ineffective?

No way, their is a reason why it's an unapproved drug, one reason could be that it can caused death unpon taking the drug, another reason might be harsh effects to the body or major side effects. So I think its better to have a patient die from a natrual cause then to force them to take a unknown drug which isn't risk free, atleast this way your perpared for when the time comes and not regretting what you did.
