Dear future hubster,
when I get old, you will have to either install something similar to those automatic food portioning devices cat owners use, or you have to instruct my doctor to only prescribe pills of different colours for me. I can't keep track of my ibuprofen vs paracetamol, I can only imagine how much fun it's going to be when I will have to remember more than two types at the time. A pink in the morning, two blues at noon and a yellow the evening?
