OOOh intersting how you have put a time on this.. because now i read this i realise that its very rare i hug people for more than 20 seconds.. and its true.. after about 5 seconds something does change in the whole experience of hugging.. suddenly were not just embracing but we enter a deep state of connection.. and i can see how that might be related to trust..

thanks for inspiring me to hug for longer! <3
