When I was about 16, I was convinced that when I am old, I will be fat and have double chin like my aunt

. I thought getting fat is inevitable with age, haha. In fact I was more fat at some points in my teenage than now..
When I am 60 I will be a wreck addicted to drugs, that´s one of the versions.
I am still somehow convinced that things only go worse with age

.
I have no idea of what will be in 20 years when I am 60, but I fear I will be left here alone without my parents and will be poor, eating potatoes and I will probably not be able to afford gas and electricity, not to say internet (in case internet and civilization still exists..). It is a very sad scenario that I have of my future, better not to think about it. I have to excercise a lot to keep myself fit so that I don´t end up like a wreck needing carers. The best would be to stay independent to my death. Oh and I haven´t mentioned that I will have to care for my parents when they are very old. I fear this a lot.
