Deadly Opposites

My grandpa died at 76 My uncle at 67 My grandma passed at 83 At 38 Aunty went to heaven My poor mom died at 66 The same year as her twin sis What evil with the bag of tricks Could be the cause of this? When dad nearly died at 71 My fate was foreseen But he revived, that son of a gun And to think I was 17 Yet at 72 he had a heart attack Though was fit at 73 We were all psyched for his comeback Plus it was doubly best for me He had no problems at 74 And 75 was a breeze Still I selfishly hoped for more But there were no guarantees Yet by god he made it to 79 Though was on the brink of death But since the reverse was my deadline I was able to catch my breath Nonetheless he died at 82 Which for him was truly great But that assured my future was through Coz I just turned 28
