Peter Foster can no longer eat through this mouth and relies on a tube for all his bodily needs. Before that he couldn't taste or smell. The 20-year-old suffers from glaucoma - which has blinded his left eye and enabled only minor vision in his right - and his lung capacity is down to 35 percent. Peter also has micropthalmia, a congenital eye abnormality resulting in small eyeballs. But, despite having over 25 diagnoses and undergoing between 40 and 60 procedures in his short life, Foster remains incredibly optimistic. Scroll down for video . Inspiration: Ben Foster, 21, has developed quite a following line, thanks to his YouTube videos that document his many medical issues. He recently had to have a feeding tube inserted in his stomach .

'Over the last couple years, my health has deteriorated, but I'm still loving life,' he said. 'I now have an eating tube in my stomach. I eat totally via tube.' 'I get weak and I get tired very easily.' 'But I hope that you guys will watch my videos if I decide to start uploading again.' 'I just want to say to thank you to anyone who still watches my channel. God bless you.' The video is quickly gaining traction online, especially on Reddit, where Peter appears to have a decent amount of followers.
