I'd been a regular comics reader from around 9 years old. As I've said before, the first time I really connected to comics and excitedly waited to see what appeared on the newsstand each month was the short-lived DC 100 pager period of the early-mid 70s. Then, my interest subsided. Certainly, I still read comics, but there was nothing giving me the same buzz that had been generated by those 100 pagers. However, they served as an indication of what was to come.
None of that really explains why I ended up being as obsessive about comics as I was from the very memorable summer of 1977 onwards, which has now persisted for over four decades. Something simply just clicked about the medium at that point; my interest just exploded in intensity, and I couldn't get enough of them. Mail order back issues, finding sources for comics that weren't distributed to the UK, going to comic marts in the city, all with a disregard for outrageous, nosebleed pricing: 75p for an X-Men 95?
The way I connect to the medium has evolved, as I now prefer to read digitally, but the obsessiveness is still present.
