  In this note, we present a pedagogical illustration of peculiar properties of
motion in the vicinity and inside black holes. We discuss how a momentary
impulse can modify the lifetime of an object radially falling into a
Schwarzschild black hole down to singularity. The well known upper limit for a
proper time spent within a horizon, in fact, requires an infinitely powerful
kick. We calculate the proper time interval (perceived as personal lifetime of
a falling observer) till the contact with the singularity, as well as the time
interval in the Lema\^itre frame (which reflects how far into the future of the
outer world a falling observer can look), for different values of the kick
received by the falling body. We discuss the ideal strategy to increase both
time intervals by the engine with a finite power.
  This example is suitable for university seminars for undergraduate students
specializing in General Relativity and related astrophysical subjects.
