         2 . The shock reduction tool of  claim 1 , wherein the wire management section is filled with fluid and exposed to ambient wellbore pressure. 
     
     
         3 . The shock reduction tool of  claim 2 , wherein the plurality of wires are disposed in at least one section of tubing in the wire management section. 
     
     
         4 . The shock reduction tool of  claim 3 , wherein the at least one section of tubing comprises a helically wound portion inside the wire management section. 
     
     
         5 . The shock reduction tool of  claim 4 , wherein the plurality of wires are divided between a plurality of sections of tubing in the wire management section. 
     
     
         6 . The shock reduction tool of  claim 5 , wherein the helically wound portions of the plurality of sections of tubing are in a nested arrangement. 
     
     
         7 . The shock reduction tool of  claim 2 , wherein the plurality of wires are disposed in a flexible hydraulic hose inside the wire management section. 
     
     
         8 . The shock reduction tool of  claim 7 , wherein the flexible hydraulic hose is tied into at least one knot inside the wire management section, and wherein the at least one knot is configured to loosen and tighten in response to axial movement of the shock absorber section. 
     
     
         9 . The shock reduction tool of  claim 8 , wherein the inside of the flexible hydraulic hose is pressure compensated. 
     
     
         10 . A measurement-while-drilling tool, comprising:
 an upper electronics module comprising at least one sensor;   a lower electronics module;   a shock reduction tool disposed between and configured to mechanically and electrically connect the upper electronics module and the lower electronics module, wherein the shock reduction tool comprises a shock absorber section and a wire management section.   
     
     
         11 . The measurement-while-drilling tool of  claim 10 , wherein the wire management section is filled with fluid and exposed to ambient wellbore pressure. 
     
     
         12 . The measurement-while-drilling tool of  claim 11 , wherein the plurality of wires are disposed in at least one section of tubing in the wire management section. 
     
     
         13 . The measurement-while-drilling tool of  claim 12 , wherein the at least one section of tubing comprises a helically wound portion inside the wire management section. 
     
     
         14 . The measurement-while-drilling tool of  claim 13 , wherein the plurality of wires are divided between a plurality of sections of tubing in the wire management section. 
     
     
         15 . The measurement-while-drilling tool of  claim 14 , wherein the helically wound portions of the plurality of sections of tubing are in a nested arrangement. 
     
     
         16 . The measurement-while-drilling tool of  claim 11 , wherein the plurality of wires are disposed in a flexible hydraulic hose inside the wire management section. 
     
     
         17 . The measurement-while-drilling tool of  claim 16 , wherein the flexible hydraulic hose is tied into at least one knot inside the wire management section, and wherein the at least one knot is configured to loosen and tighten in response to axial movement of the shock absorber section. 
     
     
         18 . The measurement-while-drilling tool of  claim 17 , wherein the inside of the flexible hydraulic hose is pressure compensated.
