I still can not understand why scientists still can't find the cure for HIV virus or TB or cure for some cancer..in this modern age, with the technology and knowledge, and funding available..still we r way back.
@Jellifish cancer is tough. My father in law (phd microbiologist) did cancer research for 35 years in the best research hospital in the country and he said they made a lot of progress but an actual cure was still a ways off. At least with HIV and AIDS they have Prep and Pep which are huge, but also not an exact cure
