My TODO list isn't public but this is what I am apparently currently working on:
[external] hadron(since 20d, open, low priority, task age: 1130d)
misc(since 139d, open, low priority, task age: 1058d, ? subtasks)

According to my estimations, completing all things on my TODO list will take me around Infinity hours.
Looking at all completed tasks, I usually take 1.01x shorter than estimated on average, so everything would probably actually take Infinity hours.
