The good news is that PLA is a bioplastic and can be broken down via industrial composting, but even still, any method that allows you to reuse... | 12 | 4 | [

In the beginning it may not be too difficult to manage, but as the disease progresses the tremors get worse and worse, until day-to-day movements are extremely difficult.
