Ok, I am reading a book about photographic and enhanced memory.
And my dad told me to fix his radio so I used a technique to link that to an emotion as well as some other tasks I had to do today.
Now I will never forget that NRD 1 (a broadcast station) is on frequency 91.1, that his radios alarm clock used to go off at midnight, said radiostation goes to button one and that I have to measure the length of my ceiling light bulb (which is is 14 cm)
I mean, it's working but: Argh.
