In the movie Forrest Gump, Jenny dies after contracting "some kind of viris" in the 1980s. Though never said specificly it can be heavily implied from Jenny's drug using and promiscuous lifestyle in the 60s and 70s could've led her to contracting HIV/AIDS. Now, Jenny and Forrest had sex after Jenny's free-spirit days in that time period and when she was trying to straighten her life out, she also has Forrest, Jr. in this time. So, did Forrest and Forrest, Jr. contract HIV/AIDS from her? Isn't this kind of a dark ending to Forrest Gump? That Forrest, Sr. lifespan has now been signifigantly reduced (and he doesn't even know it) and Forrest, Jr's life is going to be a short one as well?
