England pace-bowling stalwart James Anderson has sounded an ominous warning ahead of the three-Test series against South Africa beginning at Lord's on August 17, saying he has no plans of "slowing down", despite the right-hand quick crossing the psychological age barrier of 40 years.

Anderson, following an off-colour Ashes series which led to him and pace-bowling partner Stuart Broad being dropped from the away series in the Caribbean, returned to the side for the Test series against New Zealand and the rescheduled fifth Test against India where he met with huge success.
