Tired Brain

I enjoy that state when my brain gets tired from thinking hard when there is a way for me to take a break and do something that involves no thinking at all. It is almost as satisfying as binging on food that is delicious and bad for me. That is obviously not an option for people whose jobs require that their brains continue to think hard past that point of fatigue and the costs of making poor decision could mean the difference between life and death for someone else

The researchers found that participants who laboured on the more difficult task had accumulated more glutamate in this region of the brain by the end of the day than had those who worked on the easier task. And, given a choice between an immediate cash reward and a larger reward that would come months later, they were more likely to choose the smaller, short-term reward than they were at the start of the day.

It seems like humans should work upto the point when the break feels like an awesome reward and be given enough time to enjoy that treat so they are re-invigorated for the thinking again.

Part Liberated Woman

An expat desi friend and I were discussing what it means to return to India when you have cobbled together a life in a foreign country no matter how flawed and imperfect. We have both spent over a decade outside India and have kids who were born abroad and have spent very little time back home. Returning "home" is something a lot of new immigrants like L and myself think about. We want very much for that to be an option because a full assimilation into our country of domicile is likely never going to happen. L has visited India more often than I have and has a much better pulse on what's going on there. For me the strongest drag force working against my desire to return home is my experience of life as a woman in India. I neither want to live that suffocatingly sheltered existence myself nor subject J to it. The freedom, independence and safety I have had in here in suburban America was not even something I knew I could expect to have in India. I never knew what it felt t...

Under Advisement

Recently a desi dude who is more acquaintance less friend called to check in on me. Those who have read this blog before might know that such calls tend to make me anxious. Depending on how far back we go, there are sets of FAQs that I brace myself to answer. The trick is to be sufficiently evasive without being downright offensive - a fine balancing act given the provocative nature of questions involved. I look at these calls as opportunities for building patience and tolerance both of which I seriously lack. Basically, they are very desirous of finding out how I am doing in my personal and professional life to be sure that they have me correctly categorized and filed for future reference. The major buckets appear to be loser, struggling, average, arrived, superstar and uncategorizable. My goal needless to say, is to be in the last bucket - the unknown, unquantifiable and therefore uninteresting entity. Their aim is to pull me into something more tangible. So anyways, the dude in ques...

Changing Pace

This blog has been a big part of my life for the last five years. Besides giving me the opportunity to connect with a number of interesting people and share my thoughts and ideas with them, it has been a form of daily meditation for me. No matter what the day threw my way, I made a very deliberate effort to find a little quiet time to write.The process of thinking about what to write and then the act of writing itself worked as an antidote to aggravations big and small. Five and half years ago, when I started Heartcrossings both my personal and professional lives left a lot to be desired for. The only real happiness I had was in being J's mother. While that was often enough to make me forget what I did not have, I sorely needed a third place to call my own and shape in the likeness of my dreams. This blog has been where there were no limits or constraints and that was absolutely exhilarating - it is the reason I have been able to nurture it for as long and as much as I have. A lot ...
