30 min run/day * 365 days/yr = 10950 min/yr * 1 day/1440 min;
-> 10950 min/yr * 1 day/1440 min = 7.6 run-days/yr;
-> 7.6 run-days/year * 3 years = 22.8 run-days.
3 years = 1095 days
23 run-days/1095 days = 0.021 days ran in 3 years
TL/DR:
or, 2% of your 3 years is spent running
Perspective?
Sleep = 8 hrs/day [same math]:
==> 33% of your 3 years is spent sleeping (or making memes) ;;
looks like pretty good trade-off to me!
*Disclaimer: I run.
