I have just scared myself by looking at the sticker on the back of my microwave and realising that it was made in 1993. Assuming I bought it the same year it was made (quite possibly as so old can't remember), it is 32 years old. I read online, that you are meant to replace microwaves after 10 years.
Question is, will we have been poisoning ourselves with this ancient microwave? I have ordered a new one from Amazon, which is coming tomorrow.
