In fact, even in packs or tribes, the lone male takes off and survives on his own before joining up with another group, if he ever does.

You have an idealistic view of your fellow man, which is commendable, but unrealistic. Just ask your neighbor to pay your mortgage and all your other bills this month, so that you and your genes can survive. Let me know what his reply is. Or better yet, ask one of your relatives to take them over. That might be even more intriguing. thanks, Mark
