Yep. I concur. BN WPI. I dont like chocolate but they do have a couple of choccy flavours plus a bunch of others. I'm more of a banana man (no ghay).
Over the last few years Dave Palumbo, on his podcast, has talked a lot about his father who is in his 80's. Sounds like he's go a bit of Alzheimer's. Anyway, he pushes his dad to take his WPI as older folks tend to have no appetite. A glass of choccy stuff, or whatever flavour you like, goes down easier than a meal.
Also, just so you know, light weight training (stuff he could do at home) has huge benefits for oldies, just like youngies.
