Macbook shutdown when closed lid

ShutdownCause       	SMC shutdown cause: -82:

"Thermal shutdown for overtemp",       -81
"Proximity temperature exceeds limits" -86

Fan always spin with CPU intensive memory intensive activity
So my guess for 82 is a shutdown because temperature limit is exceeeded
Poor man fix, would be to shutdown or kill -9 any activity that hogs intensive activity 
Before closing lid

Typical offenders - check activity monitor

* mds_stores - Spotlight indexing // makes sense if did a big git update of files before closing lid
* Chrome - self explanatory
* zsh - tends to conflict with an apple update somehow and ends up eating CPU
