Is the harvest based upon this current incarnation or is it cumulative?

[AnthroHeart]

I mean I serve others when it's convenient. Like I'll give $3 to a homeless person. Or if I come across an opportunity, I won't turn it down usually.
But I'm not out volunteering at soup kitchens, or at pet shelters, or homeless shelters.

I probably don't spend nearly 50% of my time helping others directly. But others have told me they feel I am harvestable.

But then why do I think about myself and my own harvestability so much. I should be concerned with others, shouldn't I?
